I'm with your daughter, RCI is much more family/kid oriented than Princess. My wife and I have done many Princess cruises, we like the quiet, serene vibe. We've experienced many other brands as well, but for a cruise that includes our adult children, their spouses and children (aged 3, 7, 9) we also chose Adventure of the Seas. We were on her about 15 years ago out of San Juan and at the time it was huge... not so much now. But definitely a louder, more "let's get the party started" vibe. Looking forward to an exhausting time trying to keep up with the grandkids!
