We are first time cruiser and are taking our 3 kids on a Disney Cruise (age 7, 6, and 4). We are trying to decide between Western Caribbean (Key West,, Grand Cayman, Cozumel, Castaway) or Eastern (Tortola, Virgin Island, St. Thomas, Castaway). Is one strongly better than the other? We hope to not have to do expensive excursions at the Ports since the cruise itself is pretty expensive already. Thanks for all of the advice!
