We booked a cruise by accident several years ago. Seven day cruise. I figured what the heck, lets see what happens. Tons of college age kids, loud boisterous and some of the most polite kids ever. We just wandered off if we needed to be away from it but generally just enjoyed the kids antics. Gotta say, they were more inclined to apologize if they bumped into you or whatever than most of us older folks. Go with the mindset you are going to have fun and you will.
