Hi there, Regina, and welcome to planDisney!
No matter the weather, staying hydrated is very important — especially when navigating the Disneyland Resort.
Guests are
allowed to bring outside food and nonalcoholic beverages into the parks as long as they are not in glass containers. Stanley cups are not specifically called out in the
prohibited items list. As long as your water bottle is made from a non-glass material, you are welcome to bring it during your park visit!
Bonus Tip: After you make your park day itinerary, scope out the
water bottle-filling stations available in each park. We exert a ton of energy when walking around the parks; it’s important to make plans to refuel. Speaking of refueling, check out the
new foods and treats available as Disneyland continues its
70th Anniversary Celebration.
Regina, I hope this information was helpful and that you have the most wonderful time during your upcoming visit to the Happiest Place on Earth. Stay hydrated out there!
Sending you faith, trust, and pixie dust,
Karmeen
