Hey there, Mona! You've come to the right place with your planning question. Welcome to planDisney!
Hydration is a very important detail when enjoying a magical visit to The Happiest Place on Earth. I am glad to hear that you are already planning to make sure your family is prepared. You are more than welcome to bring hydration packs with you to the parks. I have seen many Guests wearing these during their visit. If you have the smaller packs that go inside a backpack or the backpack-style hydration packs, these would be just like any purse or backpack and you would carry them on with you to each attraction. Most attractions will have a pouch for each seat to place your accessories or bags or you can just hang on to them or place them at your feet depending on the attraction.
Disneyland Resort offers both
drinking fountains and bottle-filling stations throughout the park to make sure you stay properly hydrated during your visit. You can also go to almost any quick-service counter and ask for a cup of water if you prefer a nice ice-cold cup of water.
If you end up wanting to ditch some or all of your hydration packs midday, you can utilize the
locker rental locations to store some of your gear.
Mona, thank you again for stopping by to chat with us! Be sure to stop by again if you have any other questions as you continue to plan your Disneyland Resort visit. See you real soon!
