Since I don't want the kiddos to get sea sick, I am likely going to cancel the Xcaret excursion we had booked. My nieces want to swim with dolphins and I think my daughter would love it too. I know that while Disney doesn't offer any swim excursions for children my DDs age, I know we can do it at Chankanaab. How easy will it be to arrange our own transportation once we get off the boat? This may work out better for us since the start time of the Xcaret was 7:15am which would be a pain with 3 kids to get up, get ready and feed. Also, the aquarium in Key West - I have heard it's small but many people said they liked it. Is it worth going? I've been trying to find pics but can't. Any suggestions for Grand Cayman. I haven't seen much that we can bring our toddler along on - so I am thinking a beach. Is Seven Mile the best one?
