Hi there, Laura!
Being prepared for any food or drink emergency is always on the top of my list when planning my family's Disney vacation! My toddlers are always asking for a snack even while on vacation!
So, yes! You can bring in any
food items that do not require heating. I bring some my family's favorite snacks, like applesauce, chips, cookies, and sandwiches! Frozen bottles of water are a great idea on a hot day!
Just be sure to inform Security Cast Member at the security checkpoint that you have food items, but it won't be a problem at all!
Enjoy planning your vacation and if you have more questions, please visit with the Disney Parks Moms Panel again!
See you soon!
