The Essentials

U.S. passport holders enter Türkiye visa-free for tourism — no e-visa, no paperwork, just stamps at the border. It needs to be valid at least six months beyond the day we land (so beyond June 20, 2027) and have room for entry and exit stamps.

Greece is also visa-free for U.S. tourists. One new thing: since April 2026 the EU's Entry/Exit System replaces passport stamps with a quick digital record — a photo and fingerprints at the first Greek port (for us, Rhodes). It's a one-time, few-minute step at the border, handled right there; nothing to do in advance.

Europe's new travel authorization (ETIAS, a quick online form like the U.S. ESTA) is set to launch in late 2026 — but the EU has confirmed a six-month transition during which travel without it is fine. For our dates it is not required. This page gets updated weekly, so if that changes, it'll be reflected here long before December.

• Layers beat one heavy coat — mornings near 40°F, afternoons in the upper 50s.
• A waterproof layer and travel umbrella — December rain comes and goes.
• The grippiest shoes you own. This is the one to over-pack for. It isn't only the ruins: Athens is paved in marble — Plaka's lanes, the sidewalks, the steps up the Acropolis — and polished stone plus December damp is genuinely slick. Rhodes' cobbles and the marble street at Ephesus are the same story.
• A walking stick. On the list by request, and the right call — marble, cobbles and uneven ground are most of this trip, and it's the one thing that can't be picked up along the way.
• One dressier outfit covers the ship's evenings — Viking's after-6pm dress code is "elegant casual" (no ties or gowns needed).

Two restaurants aboard take bookings, and both are included in the fare: Manfredi's Italian Restaurant (aft, Deck 1) and The Chef's Table (aft, Deck 1), where the sommeliers run a multi-course tasting with wine pairings and the menu changes through the voyage. My Viking Journey currently says reservations are "not available at this time" and opens them on October 23 at noon Pacific — two in the afternoon Central, and exactly sixty days before we sail. On a Christmas sailing they will not sit unbooked for long.

Everything else needs no planning at all. The Restaurant (Deck 2 aft) is the main dining room, open seating; so are the casual venues — the World Café with its outdoor Aquavit Terrace, the Pool Grill, Mamsen's for Norwegian waffles, the Wintergarden for afternoon tea. Room service runs around the clock.

My Viking Journey closes excursion bookings and changes seven days before the voyage begins. All six of our included tours are confirmed for both of us, so this isn't a deadline we have to act on — it's the last date to add something from the paid menu, or swap a departure time. Two of ours can't be moved regardless: the Troy 10:00 AM and Rhodes 9:00 AM departures are both sold out.

Every included tour runs four departures — two in the morning, two just after midday — even though the portal labels every tile “MORNING.” Ephesus goes at 8:00, 8:30, 12:30 and 12:45; Athens at 8:15, 8:30, 1:00 and 1:15. Ours are chosen rather than assigned, and the tile is not to be trusted: open the reservation itself to see the time we actually hold.

Viking has no formal nights at all. Days are casual; after six the code is "elegant casual" — a dress, skirt or slacks with a blouse or sweater, or trousers and a collared shirt. Jeans are the one thing the evening venues don't take. One smart-ish outfit each covers the whole week, which is why the packing list above stays as short as it does.

The Neptune carries self-service launderettes on the stateroom decks — washers, dryers and irons, free to use. That is what lets the packing list above stay as short as it does: pack four or five days rather than thirteen.

Detergent is provided, so pods are optional rather than essential — worth bringing anyway if you would rather use your own.

The launderettes are busiest on sea days. Running a load during dinner is the trick.

Comfort Check-In. Viking asks for it per guest, and it's what shortens the queue at Galataport on the 22nd. It sits under Before You Go in My Viking Journey.

The Viking Voyager app. Daily schedule, deck plans, dining bookings and the stateroom account, all on a phone — and it's the thing that replaces asking at a desk. Better installed at home than over ship wi-fi.

Decide about gratuities. They're offered pre-paid in advance; settling them before we go means nothing to think about at the end.

Health & Accessibility requests. Viking take these through a form in Before You Go, in advance rather than at the desk — mobility, hearing, dietary, anything that would make a day easier. Free, and the sort of thing that is far simpler to arrange from home than on a coach at Çanakkale.

None of this is needed — listed in case anyone wants it. Silver Spirits is the premium drinks package — the fare already covers wine, beer and soft drinks with lunch and dinner, so it only pays off on cocktails and spirits outside those hours. Luggage Forward collects bags from home and delivers them to the ship. Pre-paid gratuities are the third. All three live in My Viking Journey.

The advice you'll hear is "mainland yes, islands no." That's a real rule, but none of our three Greek stops is on the wrong side of it. Nobody needs to spend the week buying bottles.

Athens draws from protected reservoirs at Marathon and Yliki and its water is among the best-rated in Europe; there are refill fountains in the National Garden and on the Acropolis hill itself. Crete has its own mountain springs, so Heraklion's tap is fine — it just tastes hard and mineral from the limestone. Rhodes Town has real rainfall and reservoirs behind it and meets standards. The islands that genuinely can't — Santorini, Mykonos and the dry Cyclades, where it's desalinated or shipped in — aren't ports of ours.

Where to stay careful: small Cretan villages and rural Rhodes, where it's bottled by default. And everywhere in both countries, brushing your teeth with tap water is fine — it's all heavily chlorinated.

At the table: in touristy streets a bottle often lands on the table unasked, and being charged for it is normal. You can simply ask for a jug of tap water instead and no one minds. If you do buy, the price of a small bottle is capped by Greek law — 500 ml can't exceed about €0.60, even at the airport.

A Greek restaurant may have two desserts on the menu, or none, and that isn't an oversight — sweets here are an afternoon occasion, eaten between lunch and dinner, and they come from a pastry shop (zacharoplasteio) rather than a kitchen. So the plan for anything sweet is a mid-afternoon detour, not a wait for the dessert menu.

The two on our route: El Greco near Syntagma, which is a few minutes from our Athens hotel, and Aretousa in Heraklion, which sits in the part of town our Crete tour finishes in. Nancy's Sweet Home by Monastiraki is the other Athens name worth knowing.

FREE NOW is the taxi app Greeks actually use — more drivers on it than Uber, and cheaper. Bolt is the other one worth having in Athens, and often the cheapest of the three. Uber works but pulls from a thinner pool, so you wait longer. In Türkiye the equivalents are BiTaksi and Uber, both widely used in Istanbul. WhatsApp is worth having in both countries; it's the default way people message.

Bounce finds somewhere nearby to leave luggage for a few hours — a disembarkation-day problem more than an Athens one. New Hotel will hold our bags on the 29th, so it is a backstop rather than a plan, but it costs nothing to have on the phone.

If we hire a car for a day — Rhodes and Crete both make sense for it, and it's the easiest way to reach Lindos or Arkadi on our own clock — two things matter. First, book through a platform rather than the rental desk: the same full-coverage insurance bought direct can cost several times what it costs through an aggregator, and the gap is not small. Second, take the full coverage. Island lanes are narrow, walls are close, and without it a scuffed wing mirror is charged at a few hundred euro. Volta, Alamo and Auto Union are the names that come up as reliable and reasonably priced locally.

One caution for our dates: on Rhodes we're ashore 7:00 to 6:00 with the tour taking the morning, and on Crete 7:00 to 6:00 with the tour taking the morning, so about six free hours from noon — enough for a half-day hire, but pick-up and drop-off eat into it, so a taxi may simply be less friction for a single destination. In Istanbul, don't drive: the old city is walkable and the traffic is its own event.

Drinking in the street is perfectly legal in Greece — a beer while you walk raises no eyebrows and needs no paper bag. But nothing except water may be carried into an archaeological site or museum, so the coffee has to be finished before the turnstile at the Acropolis, at Knossos, and at the museums. Worth knowing before someone buys a frappé on the walk up.

Toilets: free inside museums and the major sites, and scarce everywhere else — Greece has very few public ones on the street. The custom is simply to step into a café and ask. In Athens they almost always wave you through; on the islands they may expect you to buy something, at which point a €1 bottle of water settles it.

English is widely spoken in both countries and nobody expects more than this — but a greeting in the local language is always welcome.

Cards (including tap-to-pay phones) work almost everywhere in both countries. A modest amount of cash covers the rest — bazaar stalls, taxis, small cafés, tips. Airport and bank-attached ATMs are the easy source; there's no need to buy lira in the U.S. beforehand.

Tipping, roughly: 5–10% at restaurants in Türkiye. Greeks do tip too — around 10% — but only where there's actual service: a restaurant, a taxi, a guide. Nobody tips for street food or a takeaway coffee, and you shouldn't feel you have to. Onboard, anything bought charges to the stateroom account, so ports are the only place cash really matters. Gratuities are a separate question — Viking sells them pre-paid as an optional purchase before sailing, which means they are not automatically settled by the fare. Worth confirming against the booking rather than assuming (see Aboard the Neptune).

A heads-up for card users: if a terminal offers to charge in dollars instead of lira or euro, the local currency is always the better rate.

The ship's Wi-Fi is free — texts, photos, FaceTime and email all work at sea without any plan. For the days ashore, two easy routes:

• Carrier day-pass (Verizon/AT&T/T-Mobile international plans) — zero setup, ~$10–12 per day used.
• Travel eSIM (Airalo and similar) — a few dollars for the whole trip, set up in the app before leaving; best for newer phones.

Either way, both countries are covered by one choice — no separate plans needed for Türkiye and Greece.

Türkiye runs 9 hours ahead of U.S. Central Time; Greece in winter is 8 hours ahead. The fun part: sailing from Ephesus to Rhodes overnight, the clocks go back an hour — a 25-hour day, and the ship announces it so nobody has to think about it.

Both countries use the round two-pin European plug (Type C/F) at 230V. Phone and laptop chargers handle the voltage automatically — only a plug adapter is needed, and one per person is plenty. The hotel has them at the desk in a pinch, and Viking staterooms have U.S. outlets and USB ports built in, so ship days need nothing at all.

U.S. Medicare doesn't cover medical care outside the country — the standard answer for international trips is a travel-medical policy, which also covers trip interruption. Viking offers its own Travel Protection Plan with the booking, and third-party policies (Allianz, Travel Guard, and similar) cover the same ground. Worth a five-minute look if it isn't already in place.

Prescriptions travel best in carry-on luggage, in original containers, with a few days extra. The ship has a medical center, and pharmacies are everywhere in both countries (look for eczane in Türkiye, the green cross in Greece) — pharmacists are helpful and most speak English.

Istanbul Airport (IST) to the AJWA Sultanahmet is about 45–60 minutes by car. The hotel arranges airport transfers — the simplest possible landing after a long flight.

Viking docks at Galataport, the cruise terminal in Karaköy — a 10–15 minute taxi from the hotel, just across the Golden Horn. Checked bags go to the ship's bell desk and reappear in the stateroom.

We leave the ship in Piraeus on the morning of the 29th and stay two more nights in Athens. The flight home is AC 899, out of Athens at 1:00 PM on the 31st. Syntagma station to the airport is about 40 minutes on the metro, so leaving the hotel around 10:00 is comfortable.
