Carnival Revises Two 2026 Adults-Only SEA Cruise Itineraries
Both departures are part of Carnival’s twenty-two cruise SEA program, with casino-focused programming and sailings from Miami, Port Canaveral, Singapore and Long Beach.
Carnival Cruise Line has revised two 2026 adults-only SEA cruise itineraries, altering the port sequence and call times on an 11-night Carnival Firenze sailing from Long Beach and replacing one Caribbean port on an 11-night Carnival Conquest voyage from PortMiami. The affected departures are Carnival Firenze’s Nov. 2, 2026, cruise and Carnival Conquest’s Nov. 30, 2026, cruise.
Both sailings are part of Carnival’s Sailings Exclusively for Adults program, a 21-and-older product with casino-focused onboard programming. Carnival has opened four fall 2026 Carnival Firenze SEA departures to any passenger 21 or older after earlier availability was primarily invitation-based for casino players.
Mexican Riviera cruise changes port sequence
For Carnival Firenze, the Nov. 2 sailing remains an 11-night roundtrip itinerary from the Port of Long Beach with calls in Acapulco, Puerto Vallarta, Mazatlan, Cabo San Lucas and Ensenada. Carnival told guests it is changing the order of Acapulco and Puerto Vallarta. It is also adjusting scheduled hours in Mazatlan.
The Nov. 2 departure is part of the Firenze SEA series Carnival added earlier this year; the line cancelled 11 regular Firenze sailings to accommodate the casino-focused schedule. The 135,156-gross-ton Carnival Firenze carries 4,126 guests at Carnival’s listed double occupancy.
Carnival Brand Ambassador John Heald, who said he plans to sail on the Oct. 12 departure, told followers: “SEA adults-only cruises now open for everyone.” Heald said the sailing would include an enhanced dining room menu, special entertainment and casino activity.
St. Thomas replaces St. Maarten on Conquest
Carnival Conquest’s Nov. 30 sailing will call at Charlotte Amalie, St. Thomas, in place of Philipsburg, St. Maarten. The 11-night Southern and Eastern Caribbean itinerary also includes St. John’s, St. Lucia, Barbados and Grenada.
The 110,000-gross-ton Carnival Conquest carries 2,980 guests at standard double occupancy. Carnival’s broader 2026 SEA program includes 22 cruises on Carnival Conquest, Carnival Dream, Carnival Glory, Carnival Paradise and Carnival Firenze, with departures from Miami, Port Canaveral, Singapore and Long Beach.
Carnival told booked guests that shore excursions purchased through the cruise line will be adjusted automatically to match the revised itineraries. For ports no longer on the schedule, pre-booked Carnival tours will be refunded to the original form of payment.
