Hi shannon, we are booked miracle in jan. I booked with Capt marvin for sting ray city snorkle swim with rays at caymen for 39.00 ea. its about 1/2 day tour without lunch, and from what I have read on the boards the tour is alot more personel then the cruise tours, its in smaller groups, and its like a cattle drive on the cruise line tours when you book on board http://www.captainmarvins.com/
we booked right on line small deposit and you pay when you get there, also in Cozumel we may go to playa mia or paradise beach, I prefer playa mia one price for the beach gets you all drinks, buffet lunch, and use of non motorized toys, snorkling equip for the day for a price under 40.00. paradise charges only 7 or 8 dollars but you have to pay for lunch and drinks I find the playa a better deal beacuse we do drink the beer and Margaritas on the beach http://www.playamia.com/
also we are thinking of this tour if we don,t do beach, infact I think the guys want to do fury so I am over-ruled http://www.cometocozumel.com/english...s-fury-map.asp
In belize I found this company for tours http://belizecruiseexcursions.com/
we are considering the zipline adventure 80.00 each looks like fun what ever you plan have fun the ships tend to charge a bit more for the cruis tours so I would compare you can check out the excursion prices on Carnivals site to compare, and also they book out completely and may not get anything once you board whatever you decide have fun!!!
