Carnival Extends Bookings on Adults-Only Cruises

While Carnival Cruise Line takes pride in being a family cruise line, they also offer a handful of adults-only cruises each year where all guests must be 21 years or older to sail.

These sailings are called SEA cruises, Sailings Exclusively for Adults, and Carnival has several of them coming up.

The cruises will offer an enhanced dining room menu, special entertainment, and extra casino events since there are no kids on board the ship.

The cruise line has extended bookings on four adults-only cruises this fall, which must be booked by August 30, 2026. The four cruises will take place on Carnival Firenze out of Long Beach, California, with four different itineraries offered.

These four cruises that are open for bookings are:

• October 12, 2026: Seven-day cruise that visits Mazatlán, Cabo San Lucas, and Ensenada
• October 19, 2026: 14-day cruise that visits Cabo San Lucas, La Paz, Acapulco, Manzanillo, Puerto Vallarta, and Ensenada
• November 2, 2026: 11-day cruise that visits Puerto Vallarta, Acapulco, Mazatlán, Cabo San Lucas, and Ensenada
• November 13, 2026: Seven-day cruise that visits La Paz, Cabo San Lucas, and Ensenada

Carnival Cruise Line’s Brand Ambassador, John Heald, will be on the first sailing on October 12, 2026. He will be hosting special events throughout the cruise that he says will be “a massive dollop of FUN“.

This offer is available for cabin assignment and may also be available for guarantee (IS/OV/BL) cabins. If a guest selects a guarantee cabin, Carnival will assign the stateroom at a later time.

In order to book a SEA cruise, you have to visit this page on Carnival.com and sign up for free. The sailings will then appear in “My Offers” when logged into your VIFP account.

Carnival Cruise Line is also offering SEA cruises on Carnival Conquest, Carnival Paradise, and Carnival Glory in 2027. They currently have 10 of these sailings open for bookings on their website.
