We're looking into the Dolphin excursion in Cozumel (assuming DCL will be there in July). The beach they mention going to afterwards--Is it Chankanaab or Playa del Sol? Either way, is it worth it to schlep our own snorkel gear? We can save about $15 pp at Castaway, but I'd like to use it more than once if the underwater scenery is worth it. When you dock at Key West does the ship have to use tenders? Is there a deli to pick up reasonably priced bottles of water/soda to keep in the room? We fly in on Friday, stay at the MCO Hyatt and taking FL tours the next day right to the airport. I don't need much water/soda/snacks, but just a bit to keep in the room. Thanks.
