I just was on the Island Princess and the teen center was ok. Their wasn't many people my age on the Panama Canal cruise I was on. But for Alaska there will be alot more teens. You'll find alot of 16 year olds there. The Island Princess is a cool ship. It isn't just for old people. You should do the pottery class. Its so much fun. Even though you have to pay for it, you should do it. I had so much fun.
