What is the best cruise that you have ever been on?

Nicole asked:

Hi, Im 19 and my friends and i want to plan a cruise for spring break. We want to wait and skip this year because my birthday is in march, so il be 21 when we go on it in 2011. Were really excited because im the last of my friends to turn 21 so were looking for a cruise that is still nice but at the same time more of the partying type. Any suggestions? Thank you for your answers!
