Carnival Cruise Line has notified booked guests that two autumn 2026 sailings have received itinerary modifications as a result of the line's growing SEA adults-only program, which centers on casino entertainment and gaming experiences. On the 11-night Carnival Firenze sailing departing Long Beach on November 2, the order of calls at Acapulco and Puerto Vallarta has been reversed. On the 11-night Carnival Conquest voyage departing PortMiami on November 30, the ship will no longer call at Philipsburg, St. Maarten; Charlotte Amalie, St. Thomas, replaces it.
Carnival confirmed that guests who booked shore excursions through the cruise line for ports still on the revised itineraries will have their bookings automatically adjusted to the new timings, while excursions at dropped ports will be canceled and refunded to the original payment method. The SEA concept, which repurposes select voyages as dedicated casino-focused experiences, has now altered the wider schedules for both ships involved. Carnival says the changes are part of its effort to accommodate specialized cruise experiences while maintaining access to popular destinations.
