Carnival Cruise Line has added two more adults-only sailings to its 2027 lineup, expanding its SEA Cruises program.

In an update shared by Brand Ambassador John Heald, Carnival said the new sailings are open for booking through October 16, 2026.

The additional SEA cruises will sail aboard the Carnival Paradise and the Carnival Horizon, offering expanded casino access, themed parties, bingo events and other adult-focused activities.

According to Heald, the sailings were added in response to popular demand and offer an exclusive option for guests 21 and older.

Sailing roundtrip from its homeport in Tampa, the Paradise will depart on a six-night Western Caribbean cruise on February 12, 2027.

The Horizon will follow on May 13, 2027, with a similar six-night Western Caribbean voyage from Galveston.

Both itineraries include stops in Cozumel, Mexico, and at Carnival’s Isla Tropicale in Roatán, Honduras.

Carnival’s SEA cruises were introduced in early 2025 as a new product designed exclusively for adults.

At the time, the company said the sailings were designed to maximize guests’ casino playtime and onboard experience.

Initially announced for select Carnival Conquest sailings between August and September 2025, the program was later expanded to additional ships and dates.

The Carnival Glory, the Carnival Dream and the Carnival Paradise were among the ships offering adults-only sailings in 2026, with itineraries ranging from the Caribbean to Europe.

Earlier this year, Carnival canceled a month’s worth of sailings aboard the Carnival Firenze to make room for new SEA cruises on the West Coast.

Sailing to the Mexican Riviera from Long Beach, the ship will operate four SEA cruises between October and November 2026.
