9. Hydrate
This is probably the most important rule for visiting Walt Disney World in the summertime. It’s hot and humid, and you are going to lose a lot of fluids through perspiration. Drink before you feel thirsty. While there are plenty of tasty beverages in the parks, nothing is better for hydration than plain old H2O. And it’s free! Just ask for a cup of ice water at any quick service dining
location.
