Hi Eliza, welcome to planDisney.
Pools and splash pads, which are typically adjacently located, are only available to be used by the overnight Guests of that Disney Resort hotel. The great news is that you will find many little splash areas for your little ones within the Parks and Disney Springs that you can use.
In Magic Kingdom Park, you'll find some splash-tastic fun at
Casey Jr. Splash 'N' Soak Station in the Storybook Circus area of Fantasyland. As you're visiting with Little Mouseketeers, I'm sure a change of clothes is already in your Park bag, and that change is likely to be needed after this water fun. EPCOT offers various fun water features, but the newest and most delightful is
Journey of Water, Inspired by Moana. You can go with your water flow on this exploration trail where water comes alive! Disney Springs has two splash pads available for kids to enjoy. One is located near Earl of Sandwich, and the other is behind the Christmas store.
And finally, for the ultimate in splash-tastic fun, there's Disney's Water Parks. Did you know that entrance to
Disney's Water Parks will be complimentary for all Disney Resort hotel Guests on their check-in day from 2025? You could cool down at
Disney's Typhoon Lagoon or
Blizzard Beach Water Park (at the moment, one is open at a time), frolic in the waves, splash down some rides, and float on a lazy river! The perfect way to relax after a busy morning in the Parks.
I'm sorry if this wasn't quite the information you wished for, Eliza. I hope you agree that it's best to be correctly informed so there's no disappointment on the day, and that you still enjoy the magical fun of water!
Louise
