Howdy Melissa!! I LOVE this question!!
You and your party are going to have an amazing vacation!!!
I have spoken with numerous Cast Members as well as Disney enthusiasts and I have not been able to find accommodations that exactly match what you are looking for.
I would suggest that you contact Disney Resort Hotel Reservations at (407) 939-1936. Tell them a little about your family and what you are looking for and the Cast Member will be able to assist you in finding the accommodations that have availability and will meet your needs.
The pools at Walt Disney World Resort are all so amazing!! We do have some favorites and they are at resorts that have villas and/or family suites so they might be perfect for you!!
Stormalong Bay at Disney's Beach Club Resort is fabulous!! You will find a 3-acre water wonderland that includes a lazy river, 230-foot-long waterslide and a sand-bottomed pool. (It's my 4 year olds favorite!)
The Big Blue Pool at
Disney's Art of Animation Resort is incredible! It has underwater speakers with audio you will probably recognize. Can you find Nemo?
The Paddock Pool at Disney's Saratoga Springs Resort & Spa is great for the kiddos in your party. It has zero-depth entry and an aquatic play area that has 2 small kid-sized waterslides.
You have so many options! I'm so excited for you!!
Thanks so much for your question and please let me know if you need any further information as you plan your vacation. Have a magical day!
