Hi there! We are travling to WDW with our 2 1/2 year old and I'm not sure what to pack or buy for her to enjoy the pool? Is she old enough for a safety vest? SI believe she is too young for just swimmies and too old for those tubes that infants sit in with the sun shade. Anyway, I want her to enjoy the pool but still be safe! Any moms or dads have suggestions or tips??? THANKS!!!
