I'd like to ask for some advice. DH and I (alone) are going to the western Carribbean on the Fantasy in Jan. We want to snorkel, see Mayan ruins, and see Stingrays, I'd also like to get some shopping in at Grand Cayman. We are going to parasail on CC and plan on spending the rest of the day on the beach. Any advice on which ports to do each activity? Thanks.
