I agree about the counsulars but at least on my last cruise (we just got back on saturday) the activities weren't that great... mabey it was because we went on a double dip cruise and there wasn't enough time for a lot of activiies. I really liked the teen wildeside excursion though.
my only complaint about the stack was that they didn't split you up at all, so you didn't know who was in your age group, (most people were older than I was- i'm 14) altogether there was like 14 or so 13 and 14 year olds but no one really came after the first day.
