Set sail off the coast of Mexico on a fully-functioning cruise ship with a full-service casino, spa services – and Weezer. The alt-rock band is launching their first cruise, set to sail January 19-23 in 2012.

Guest bands include Dinosaur Jr., Sebadoh, Gene Ween and Dave Dreiwitz, Wavves, The Antlers, Yuck, Free Energy, Boom Bip, J Mascis, Lou Barlow, Keepaway, Ozma, The Nervous Wreckords, The Knocks, Sleeper Agent, and Yacht Rock Revue.

An outdoor Lido deck and indoor theater will serve as venues for the performing bands, who will entertain cruisegoers in a festival-style fashion. The ship, Carnival’s “Destiny,” features pools, hot tubs, and a waterslide.

Every cruise goer will get a photo with Weezer, an opportunity to attend a Weezer Q&A on the Lido deck, food including restaurant and 24-hour room service and non-alcoholic beverages. A day in Cozumel will precede the voyage back to Miami.

A new and more detailed website will launch on July 19. In the meantime, fans can sign up for the pre-sale here.
