bumping 12 1/2 year old to Teens activities on CC

[ClarabelleCow]

I know I posted this elsewhere, but while on Castaway Cay, what are the chances of my 12 1/2 year old daughter being able to join the older kids at Castaway Cay to do the activities on the teen beach, I understand there are alot of "sporty" water things that they do, like banana boat rides, kayak, tug or war, etc, she is almost 5'6", they probably wouldn't even realize she was only 12, but of course she will be registered as a 12 year old.
