Hi Marlene,
Thank you for stopping by the Disney Parks Moms Panel with your question. I am happy to see you are planning ahead, staying hydrated while at Walt Disney World Resort is very important, dehydration can make a fun visit not so magical!
Guests are able to bring in outside food, snacks, non-alcoholic beverages and water, provided they are not in glass containers into all of the Theme Parks. A full list of
prohibited personal items that guests are not allowed to bring into Theme Parks is available online. My family always packs a few water bottles each day, to make sure we are staying hydrated. If you do not want to carry anything extra, most Quick-Service Dining Locations throughout the four Theme Parks will distribute cups of water at no cost.
When you arrive at each Theme Park, a Security Officer will check every guest's bag upon entry and re-entry. If you do have a glass bottle, they will not allow the bottle to come into the Theme Parks with your family. The only exception to this rule is for baby food.
I hope that answers your question, Marlene. Please let us know if you have any other questions, we are always happy to help.
Stephanie
