The music festival-at-sea, which features 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, has announced the first batch of onboard activities and more special pricing options.

Besides checking out the performances on four stages through the day and night aboard the Carnival Destiny, cruisers will also get a rare chance to see their favorite musicians off-stage as well. Weezer's Rivers Cuomo is set to do a reading from the Pinkerton Diaries. Brian Bell will host p.j.s and robes "Movie Night," Pat Wilson will host a shuffleboard tournament, and Scott Shriner will lead couples through wedding vow renewals.

Attendees can also participate in fun themed activities such as an "Ugly Sweater Night," "Weezer Karaoke," and more. For those feeling a little more competitive, there will be bingo, "Weezer Team Trivia," a cannonball and belly-flop contest, plus a flip cup tournament. Weezer will also hold a Q&A session. A continually updated list of cruise activities can be found here.

Between the many shows taking place on the four stages around the ship, Weezer fans will have the opportunity to see the band play both The Blue Album and Pinkerton in their entirety. If that's not enough, attendees will be able to vote on songs they will hear. Already appearing in the rarities set, Weezer will for the first time ever play the song "Tragic Girl" and, for the first time since 1997, play "Mykel and Carli." As a thank you for all those onboard for coming, all attendees will get their photos taken with Weezer during the cruise.

When not rocking out, enjoying one of the myriad of themed events, or going on "pub crawls," fans can take in the ship's amenities like a massage in the spa, riding the water slide, or ordering from the 24-hour free room service menu. After a day-and-a-half at sea, guests have the option of spending their Saturday soaking up the sun on Cozumel's beaches before returning to sailing the Caribbean for more music and fun.

Based on fan feedback, Weezer and their cruise partner, Sixthman, have set up special 4-pack pricing. Now, fans and their three closest friends (or family members) can jump onboard for a price of just $499 per person. Click here for more detailed pricing information. All that is needed is $299 at the time of booking to join the biggest Weezer party the seven seas have ever seen. Due to popular demand for single rooms, Sixthman has introduced the "Independent Traveler Program." For more details, visit here.
