Ooh! So jealous that you are doing the 5-night - 3 nights definitely left us wishing for more! Can't wait to hear how your cruise goes!
Thinking over everything we did - I can't think of anything that I wished we had with us...if anything, I had too many clothes - but part of that was because we were in Orlando for 5 days before the cruise, and we were able to do laundry at our rental house - so we had plenty to wear! I brought fleece sweatshirts for the kids in case it was cool in the evening on deck - but I definitely didn't need them - just a windbreaker was enough on pirate night for the breeze. One of my favorite cruise necessities to bring is my toiletries case that is flat and has a hook to hang it up - very convenient! I'm also glad I purchased a couple of disposable waterproof cameras to use on
Castaway Cay - I used them while we snorkeled, and also while I was floating, watching the kids play in the water - I could snap photos without worrying about my regular camera getting sandy or wet.
