Sailing by yourself on a Disney Cruise just got 25% more expensive. Previously, single supplement was 175% of the full fare adult base rate. Effective immediately, all new bookings for solo travelers will be priced 200% of the full fare adult base rate. Existing reservations will not be affected by this policy change, unless there is date or itinerary change.
At this point, why not invite someone to join you. It would be one nice present!
