catamaran Snorkel: Rendezvous key beach break

Has anyone ever gone on the Catamaran Snorkel: Rendezvous Key Beach Break? What did you think about it? It is a boat sponsered excursion that picks up right at the boat (no tender needed). I am going to be on the Sun in December and am attempting to find something fun for everyone (ranging in age from 6-60). Usually we set up our own excursions rather than using the cruiselines, but the long tender in Belize makes me nervous about taking our large group over without plans.

joemedic .... We have also been interested in this Rendezvous excursion. There's a thread on this very board that we have found helpful (scroll):
