Hello there, friend. Thanks for stopping by planDisney!
With these warm days, it is fantastic that you are looking to stay hydrated during your trip. You are welcome to bring your water bottle into the park! My family has brought ours with ice water before with no problem. However, Cast Members at security may need to do a more thorough screening of anything brought into the parks. Loose ice cannot be brought in
coolers to the
Disneyland Resort, though we have not had any difficulty bringing in our water bottle filled with ice water. It's entirely up to the Cast Member's discretion, though!
Did you know you can locate all the water bottle filling stations using the
Disneyland Mobile App? Click on the magnifying glass icon at the bottom of the home screen and search "Bottle Filling-Stations." Click on the search result and it will bring you to a page that says "Find on Map." And, voilà! You can see where to refill your bottle. My family uses these every visit, and it's one of my favorite ways to save money in the parks.
I hope this helps! Please let me know if you have any other questions. I'd be happy to help!
