Hi Alexander! Welcome to the Disney Parks Moms Panel!
It looks like you will be visiting the Walt Disney World Resort in just a few days. Woohoo!! Are you so excited? I'm super excited for you!
First, you have the dimensions correct -
coolers cannot be larger than 24" long x 15" wide x 18" high. If a cooler
without wheels is at or smaller than those dimensions, it can enter the theme parks. As for coolers with wheels, I spoke with a Cast Member recently and was told that it is ultimately up to security, but really coolers with wheels fall into the same category as wagons and that makes them a no-go in any of the Walt Disney World Resort theme parks.
I suggest you try to take in a cooler that meets the size requirements without wheels. This will ensure that you are able to enter with your cooler full of yummy food and beverages for your day exploring the theme parks. Keep in mind that alcoholic beverages and glass containers (excluding small containers like baby food jars) are also prohibited items.
Enjoy your
Incredible Summer vacation, Alexander! Please let us know if you have any other questions!
