Hi there, Chelsea!
I’m glad you are planning on staying hydrated during your visit to the Disneyland Resort. Yes, hydration packs of various types are
permitted in the Disneyland Resort theme parks and at the
Downtown Disney District. I frequently see these types of packs being used by Guests at the Disneyland Resort. According to the
Disneyland Resort Rules,
outside food and nonalcoholic drinks are allowed. Some things that are not permitted in the theme parks include large coolers, loose ice, and glass containers.
If you are looking for other refreshing ways to cool down, I’ve got a couple of recommendations. The Key Lime Pie Slush is a current seasonal offering from the
Galactic Grill in Tomorrowland. I liked this one so much, I ordered it twice during our visit to the Disneyland Resort last week. And it even comes with a light-up glow cube! In Disney California Adventure Park, I like to wander over to
Bing Bong's Sweet Stuff located at
Pixar Pier. There, you will find sweet
Memory Refreshers. One of my favorites is the Imaginary Pal. But watch out for brain freeze!
I hope you have a magical time at the Disneyland Resort, Chelsea!
