I had sworn I had heard no devices, so I left the water wings at home. When we got to the pool at ASMo, there were a few kids wearing them. I asked the lifeguard, he said they were fine. He said we could borrow a life jacket in the arcade, or use wings. As it turns out they sold water wings in the gift shop, so I bought 2 pairs and we used them the entire trip at ASMo and BC. Now I only wish they had WDW water wings instead of just generic ones, they would have made a memorable souvenier.
