Hi Kimberly!
Thank you for bringing your question to the Disney Parks Moms Panel!
The
Walt Disney World water parks do allow Guests to bring swim floats (or "floaties") and goggles to use during their visit. There are a few attractions, mainly the bigger water slides, that don't allow them, but I don't think your children would be riding those yet, anyway. Both
Disney's Typhoon Lagoon and
Disney's Blizzard Beach water parks also offer complimentary life jackets if that is something you would be interested in.
Obviously, safety is top priority at all parks, but especially at the water parks. Even with lifeguards on duty and the use of flotation devices, it's super important for all parents to keep a close watch on their little swimmers. So definitely plan to bring their floaties if that's what they're used to swimming in!
I hope this helps! Please let me know if you have any other questions.
