Hi Monica!
Thank you for bringing your question to the Disney Parks Moms Panel!
Walt Disney World's Water Parks are so much fun! The theming at both parks is great and there are attractions for all ages. This summer, you can also experience
Disney H2O Glow Nights, a nighttime celebration with all of our friends from Toy Story, hosted by Dinosaur Rex. This event takes place every Thursday and Saturday from June 21 to August 11, 2018.
Currently, towels and lockers are available to rent at
Disney's Typhoon Lagoon (at Singapore Sal's and High 'N Dry Rentals) and
Disney's Blizzard Beach (at Beach Haus and Snowless Joe's). If you are staying at a Walt Disney World Resort, the towels are complimentary. Be sure to have your MagicBand handy so they can scan it to confirm you are a Disney Resort Guest. Towel rentals for Guests staying off property are $2 per towel, with prices subject to change. With that being said, you are welcome to bring your own towels if you prefer.
I hope this helps! Please let me know if you have any other questions as you plan your trip.
