I sailed on Princess years ago (and a few others) and liked Princess. Within the last few years we started cruising again on RCI and since I have a son now (and one on the way) I think RCI is better suited for families. Princess did seem more refined (years ago so things may have changed). RCI has a lot to offer kids 3 and up-good kids club (will be trying it for the first time this holiday season), and the Voyager ships have so many activities (rock wall, inline skating, ice rink, arcade, mini golf, basketball, etc). We are trying the Radiance class this time and are looking forward to a smaller ship with a kids pool & waterslide on board! The big ships are nice, and so spread out you really dont notice the huge number of people on board. We're just ready for a change. Ive though about trying Princess again, but we're making our way up the Crown and Anchor Society ladder (slowly)!
