Hey there, Hi there, Ho there, Edel Clarisse,
You're as welcome as can be here at the Disney Parks Moms Panel, so thanks for bringing your fantastic question.
I'm happy to let you know that water bottles and outside snacks are permitted inside the Disneyland Resort theme parks. Just make sure to take a peek at the
Park Rules before arriving so you know exactly what is allowed. All items brought into the parks will also be searched prior to entering. I like to keep small packaged snacks like granola bars or apple sauce pouches for my preschooler in case he gets hungry while we are waiting in line for attractions. I also always recommend bringing a refillable water bottle as it is often easy to forget to stay hydrated when you are busy making magical memories at the Happiest Place on Earth! You can also get complimentary cups of ice water at all Quick Service locations in the park which you can use to fill your water bottle.
I like to
rent a locker for the day to keep some of my snacks, extra layers of clothes for cooler evenings, and any souvenirs I purchase throughout the day. I love that for one low price per day you can access your locker as many times as you'd like.
I hope this helps, and please return if you have any other questions as you plan your trip. Have a Zip-a-Dee-Doo-Dah day and see ya real soon!
