Start with the membership fee, then add mandatory taxes, port expenses, gratuities, transportation to the port and any other charges for every trip. Compare the full cost with ordinary bookings for the same dates, guests and cabin type.

Confirm eligible ships and sailings, how far ahead you can reserve, blackout dates, cancellation penalties and how many reservations you can hold at once. Get the current written terms before paying.

Work schedules, travel time and available cabins determine whether a membership makes sense. Divide the annual fee by the real savings per comparable sailing, then round up to find your break-even number. If the savings are zero or negative, the fee cannot pay for itself.
