A week among the Greek islands is the rare case where getting there from the US can cost more than the cruise itself. Seven-night sailings from Piraeus start around $900 per person; the round-trip flight to Athens runs $800–1,500. Plan the two together, or the airfare will quietly choose your dates for you.
The fare, by season
The season runs roughly April to October. Typical per-person fares for a seven-night round trip from Athens (Piraeus), two sharing:
| Months | Typical fare | What you get | |---|---|---| | April–May, October | $900–1,300 | Mild weather, thinner crowds, the year's best value | | June, September | $1,200–1,800 | Warm sea, long days, the sweet spot | | July–August | $1,500–2,500 and up | 35°C heat, packed ports, peak fares |
These are mainstream-line figures for interior and oceanview cabins; balconies run $1,500–3,000 across the season. The Greek specialist Celestyal sells shorter three- and four-night sailings below these totals, and the luxury small ships sit far above them. Our fare database puts the Mediterranean median at $108 a night — but with a 43-fold internal range, because mass-market and luxury fleets sail the same water, as laid out in what a cruise costs, region by region. In this region, hunting for value genuinely works.
Flights
Athens round trip from the US runs $800–1,500 depending on season and how early you book; June through September sits at the top of that range. Two rules save real money and real stress. Book three to five months out. And fly in at least a day before the sailing: a delayed connection should not decide whether your cruise happens, and the Acropolis deserves the extra day anyway. A decent Athens hotel in high summer runs roughly $120–200 a night.
Tips
Mainstream lines add $17–18 per person per day in gratuities — about $120 for the week — plus 18–20% automatically on bar and spa bills. Some European-based lines bundle or reduce these; check the policy before comparing two fares, because a week's tips for a couple is a $250 difference hiding in the fine print.
Excursions
Greek island ports are kinder to the independent traveller than Alaska's. Mykonos town and Rhodes old town are walkable from the ship; Santorini is a tender port where the cable car and the local bus reach Oia for a few euros. The honest truth is that half the excursions sold on these itineraries are bus rides to places you can reach yourself — the exception worth booking is a Santorini caldera catamaran, which is genuinely better from the water. Where the ship's desk does earn its premium: anything timed tightly around all-aboard, and Crete's Knossos in peak heat, where a guided morning visit beats queueing at noon. Our Greek islands guide matches each island to the traveller it suits.
The cost nobody tells you about
The cruise is the cheap half. Add it up: flight $800–1,500, one or two Athens hotel nights $120–400, port transfers, and the meals ashore you will rightly want. At the budget end, the ground package exceeds the fare. The second quiet cost is tourist pricing on the famous islands: a waterfront table in Santorini or Mykonos charges two to three times what a taverna one street back charges for the same grilled fish. This is the oldest rule in Mediterranean travel and it has not stopped being true.
The all-in picture
Per person for a week, flights included, from most of the US:
- Careful budget: about $2,400 — shoulder-season interior, one Athens night, ports self-guided.
- Comfortable mid-range: $3,000–5,500 — balcony, June or September, a tour or two, dinners ashore.
- Small ship or luxury: $7,000 and up.
The day-by-day shape of the classic week is in our Greek Isles route guide, and current Mediterranean sailings are tracked in our fare database.
The short version
