Carnival Cruise Line welcomes passengers of all ages, but you can also book an adults-only cruise. However, an invitation is required.
The cruise recently added four new Adults Only Sailings (SEAs) to the Carnival Florence ship. The cruise line told USA TODAY that the cruise will sail from Oct. 12 to Nov. 20 from Long Beach, Calif., with a mix of ports on the Mexican Riviera.
Carnival plans to operate a total of 22 Southeast Asia cruises in 2026, including the Carnival Conquest, Carnival Dream, and Carnival Glory ships, currently available from Miami, Port Canaveral, Florida and Singapore, and Long Beach.
“SEA cruises are designed to offer a more relaxed, adults-only atmosphere and offer elevated dining, entertainment and onboard experiences,” Carnival said in an email. “Carnival Florence will also expand our SEA cruise options on the West Coast.”
The itineraries, first offered in 2025, include themed parties and expanded access to casinos, according to the company’s website. Passengers must be 21 years of age or older.
However, travelers cannot book it like any other cruise. Voyages are billed as “by invitation only.”
The landing page states, “If you qualify, you’ll receive an SEA cruise invitation straight to your inbox,” and includes a link to view individual offers. “(You can also find personalized offers). This allows you to explore an exclusive selection of eligible cruises.”
Carnival did not provide details on how invitations would be distributed or the starting price, but said, “Demand for these cruises continues to be strong and sell out quickly.”
