Carnival and to a lesser extent, Royal Caribbean are the best lines for young single cruisers. Just to let you know, all major cruise lines have an age restriction that people under 21 must be accompanied by someone over 25. While exceptions are made, (e.g. honeymooners), don't count on it. These policies were implimented about five years ago after several groups got out of hand and ruined the cruises of many other guests. Hope you have fun!
some of my frat brothers and i are doing the princess cruise from puerto rico in late march. Its 18+, but im not sure how easy they are on drinking (we are all 20). shouldnt be a problem if you have some 21+ brothers though. For us its a bit risky.
Me and 4 other single girls are headed out on the Norwegian Sky for the 14th of March (it was the best rate we could find) We are all over 21, so drinking is no problem, but if you really want to party I hear drinks on board are expensive, so pick a cruise with lots of port calls! (then you don't have to worry about the age!) Hope to see some other Spring Breakers on board!!!
Kevin, just better be careful, man. At least with the travel agent my friend and I dealt with. Shes strictly imphasized the importance of my friend and I being 21+ to cruise alone, which isn't a problem since we're 22 and 21, respectively. Make sure you check the cruisline's policy on age. You can have the entire trip paid for, and whatnot, and when you go to embark the ship and they see you're under age, they won't hesitate to refuse you entry to the ship. Not to mention you won't be able to get your money back.
Will be on the Glory for the March 12th (2005) sailing. Just 2 of us but others may join us. Looking forward to meeting some new people. Last year we were on the Victory for SB and had a great time. Hope you all make it out.
My brother and I (both at ASU) are going on the Vision of the Seas on March 13th to the Mex Riv... I hope there are some spring breakers on this boat... Don't want to be stuck the whole time with the parents. Let me know if anyone else is going on this boat or will be at our ports during the same week.
