Hello Karen and thanks for bringing such an important question to the Disney Parks Moms Panel.
Some of my happiest and fun times have been spent with my own dear family at either
Disney's Blizzard Beach Water Park or my personal favourite,
Disney's Typhoon Lagoon Water Park where I especially can't wait to try for myself the brand new for Spring 2017 -
Miss Adventure Falls!
I'm happy to share that towels and lockers may indeed be rented at both Disney Water Parks at
Singapore Sals & High & Dry Rentals at Typhoon Lagoon or from
Beach Haus or Snowless Joes at Blizzard Beach.
You might also be interested to know that from May 26th to August 13th 2017 Guests are invited to take part in the
Frozen Games at Blizzard Beach. Join Team Kristof or Team Olaf in a some frozen fractal fun with
chilltastic sounding games like Snow Ball Toss or Ski Pole Limbo.
Wishing you magical upcoming visit to Walt Disney World Resort.
