Yes, I am at work and mentally packing for my 3 day Wonder cruise in May. I like to plan ahead. I'm wondering if it's necessary to buy and pack my DS (6) a life vest. He's always swam in pools wearing one of those vest that zip up the front and have floation all around. I remember taking it Blizzard Beach a couple of years ago and he never needed it due to the types of things he was doing. We did use it at the hotel pool of course. For those of you with non-swimming kids do you pack one for the water areas on the boat and for playing in at CC?
