Plan to dress in layers. Take a waterproof jacket to go over the layers. The kids seemed to use the pools more than adults. The pools are heated, so maybe swim suits. We had a toddler and an infant along and did laundry in the middle. I recommend Purex 3 in 1 sheets if you want to do that. We also dressed up a little for dinners, mixing and matching so as to cut down on volume in suitcases. Camera, of course, and we used our binoculars. Have fun. It's a great trip!
