Hey, Mona!
Welcome to the Disney Parks Moms Panel. I am so glad you stopped by with this very important question. Why is this so important? Because sometimes you want your food/beverage hot and sometimes you want it cold. Being able to travel the way you want is one of the best aspects of a Walt Disney World Resort vacation.
According to the not-so-secret
Walt Disney World Resort Park Rules, you may bring your travel thermos with you inside the theme parks. Just know that Disney reserves the right to prohibit any item.
Disney Dad Tip: Disney will not fill up your travel thermos but will give you free cups of water at all
Quick Service dining locations that you may pour into your thermos.
Mona, we are ready and waiting for any future questions you have to help make your Walt Disney World Resort vacation filled with pixie dust.
Enjoy making many Magical Memories!
