Just be sure NOT to forget to pack them. We forgot DD's "water wings" a couple of years ago (she was 2). They don't sell them anywhere on WDW property. We tried to use a life vest with her, but she just kept tipping over face first. She was much more comfortable with her water wings. We went back last year & she had them @ Stormalong Bay (B & YC). No problem, she wore them going down the little kiddie slide.
