Where to buy pool floats near WDW

[DVCinderella]

I'm looking for suggestions on where to get pool floats at WDW. I'll need one with the leg holes that can accommodate almost 30lbs. Most of the floats I've seen for the 1-2yr range only go up to 25lbs.

We will have a car during our next trip, so I can shop off-property. I figure I'll have better luck finding pool floats in the Sunshine State than I will in NJ.
