Hi there, Alex! Welcome to planDisney and thanks so much for visiting us with your question. We're always happy to help you plan your next visit to 'The Happiest Place on Earth!'
What a great idea for your group to bring some snacks with you to visit the Disneyland Resort theme parks. I have often done this for my family, and it's wonderful to have access to a few quick bites and a way to stay hydrated. Indeed, coolers that you plan to bring inside the theme parks must not be larger than 6-pack-sized. However, Guests may store coolers up to 19" wide x 24" high x 31" deep in the
lockers located outside of the Disneyland Park main gate entrance. These jumbo-sized lockers are available for rent, although they are subject to availability and unfortunately are not refrigerated.
I should also mention, Alex, that loose ice and dry ice are both on the
list of items not permitted inside Disneyland Resort, so I recommend you bring some reusable ice packs to help keep your items cool, if needed. Ultimately, the final decision is up to the Cast Members at security but I also suggest reviewing the
Park Rules and Regulations in advance so you can best prepare.
I hope this is helpful for now, Alex! I'm also going to share a few more
tips for making plans with a large travel party here, in case they're useful for you. In the meantime, I wish you and your loved ones a fabulous trip full of delightful memories! Don't hesitate to come back to
planDisney if we can help with anything else that comes up.
Blue Skies and Sunshine,
