We just returned from the Carribean Princess on 10/9. We had a great time and we are 27 and 32. I have cruised on Carnival once before (without hubby) and I would have to say the entertainment is better on Carnival but the food without a doubt is better on Princess. The crowd definitely seemed older on the Princess but there was so much to do it didn't seem to matter. The main nightclub (21 and over) was not that busy on the Princess BUT by the time we did a full day we were wore out by midnight. I was actually impressed by the cabin size on Princess, especially compared to Royal Carribean. We were with a group of 8 and two of the other couples said they won't do Princess again because the staff just wasn't as friendly as Royal Carribbean....I would do it again in a heartbeat. We paid about $530 per person and felt we got a FAB deal! Hope that helps somewhat!
