I was on Royal Caribbean about two weeks ago. The ship was at sea during New Years so all the 18 year olds were able to enjoy the free champagne that Royal Caribbean was giving out. I don't think there was a single person whose age range was 18-20 who wasn't completely wasted. It was so disgusting. I guess they wanted to take advantage of being able to legally drink for the first time in their lives. The worst part was trying to sneak my drunk younger sister (19) into the cabin at 4am so that my parents wouldn't hear her.
