If it were me, I'd choose the Belize, etc. rather than the one that includes Grand Cayman. Not that I don't like GC (been there twice), but it just seems that the amount of time spent on the island isn't worth the trip. Between waiting to catch a tender (there and back) and the short amount of time in port, unless you do a planned excursion there's not enough time to really "get to know" Grand Cayman. Also, it's a fairly modern, commercialized port that seems to cater more to the shoppers and the folks wanting to swim with stingrays than to those who want to experience a different culture.
