Our first Disney cruise is drawing ever closer - July 3 on the Wonder! I've gotten a lot of great ideas and advice from this forum - thanks a bunch! One question I thought of last night while packing my sunscreen and beach hat: When we get off the ship at Castaway Cay, can we walk to Serenity Bay Beach from there? We are pretty energetic and would love the exercise instead of waiting on a shuttle, if it isn't too far. Any ideas on mileage? Thanks!
