We recommend you budget €250-500 per person, per week. That includes all food and drink related expenses.
For hostess and half-board charters you’ll only need to pay for dinners on the islands. Most of our guests find the dinners to be very affordable (€15-30 per person for a large meal including wine).
For charters without a hostess, you'll likely need €150-200 per person for breakfast, lunch, snacks, and non-alcoholic drinks for the week.
