Hello there, Ralph!
Welcome to planDisney, it's nice to meet you! It looks like you're planning to be in the parks very soon, I hope it's a fantastic day!
Yes! Guests are welcome to bring filled plastic water bottles into the theme parks according to the
Park Rules and Regulations. My water bottle is one of the "must-have" items in my park bag! I like to put lots of ice in my bottle and then use the
bottle-filling stations throughout the parks. Since refilling your bottle is easy, I don't recommend bringing a large one since water is heavy. Just a small bottle that you can refill is great!
I also recommend keeping a small bottle of sunscreen, a couple of bandages, and a pair of sunglasses in your park bag. "Luck favors the prepared!" as Edna Mode would say! If you do forget any essential items you can always ask a Cast Member at a larger retail location, like the
Emporium on Main Street U.S.A. if something is available to purchase. I've also been able to get over-the-counter medications through
First Aid in a pinch.
Stay hydrated and enjoy the parks, Ralph!
Keep moving forward!
Amanda
