Hi Elsie!
This is a great question! The answer is not everywhere, but plenty of places do. Complimentary ice water or just cups of ice is available at any
Quick-Service restaurant location or snacking spot that serves fountain soda and not bottled drinks. We sometimes bring in our own drinks and will ask for cups of ice so we don't have to worry about keeping them cold during the day and I always take advantage of the complementary ice water, which is a great way to save money!
If you're looking for ways to cool off, I highly recommend a cooling towel. I was skeptical of these at first, but they really do come in handy when it's hot outside. You just wet the towel, wring it out, waft it around a bit and place it anywhere you need cooling down, which is usually the neck for me. You can purchase them at home from Amazon or Walt Disney World sells cute Mickey themed ones.
Please stop back by if you have any additional questions.
Have a magical day!
Leslie
