I've been on 8 Carnival cruises and one Alaska Cruise in 2008 (don't remember which line though LOL
All of the Carnival ones were on a chartered cruise called
The Rock Boat. Basically they take off all the boring regular cruise entertainment and replace it with 3 stages and 20ish bands that play from noon til they pass out LOL Kinda like a floating music festival - and you don't have to worry about driving home every night!
