I figure I owe some info since I asked so many questions here before my trip. Our itinerary (DH, DS, & DD - 7yrs): Key West (on our own) - jet ski & walked around town - FUN! Grand Cayman (on our own) - Rays/Reef/Rum tour thru Native Way - AWESOME! Cozumel (on our own) - dune buggy tour thru Cozumel Homes - Don't think I would do again but the experience was nice Castaway - jet ski - AWESOME! I'll leave it brief unless someone has a specific question. Thanks to all who provided information to me previously!
