We are going to Disney World in August and plan on going to both Blizzard Beach and Typhoon Lagoon. This will be our first time to visit the water parks and I have a couple of questions for those of you who have visited the water parks. Can you wear swim shoes on the water slides and attractions or do they have you take them off? Also, do most of you bring your own beach towels from home or just rent the ones at the water parks? I thought I would bring my own towels but they will also take up a lot of room in the suitcases. Any information any of you can offer would be greatly appreciated!!! Thanks!
