Don't understand why you would say this. Although too old for the teen club (rightly so - they are normally out of high school and don't belong with 13-17 year-olds), anyone 18 and over can do anything on board. They can go to shows, bars, nightclubs, enjoy sports activities. The only thing they can't do on a US departing cruise is drink alcohol. Lots of people who are "adults" don't drink alcohol or need alcohol to have a good time.
The 18-21 age group is really in a warp when cruising; too old for the teen club, too young to do most 'adult' things.
