I've worn Crocs to both waterparks during our last visit to WDW. I love them. Previously my family had worn the Land's End water shoes which caused blisters on each of their feet. I will say that the Crocs are no good for swimming, but walking from one area to another or walking in the water they were great. Never had an issue with slipping and they're easy to dry off. Water shoes also don't offer enough support or cushion for me. You will be made to take them off on the waterslides, but not really an issue for me. I might be one of the few who likes the Croc, but that's my answer and I'm sticking to it.
