Hey, hey ShaKayla, and welcome to planDisney. I am excited to help you with your bag question and I promise to be transparent with my answer so it is crystal clear.
Here is the good news. Bags made of all materials are welcome as long as they are not included as a restricted item in the
Walt Disney World Resort Property Rules. For example, bags larger than 24" long x 15" wide x 18" high are not allowed in theme parks. You may bring a see-through stadium bag or a regular backpack whichever is easiest for you. Remember you will be walking a lot so comfort is important and the attractions only have so much space to store your bag. Guests with many items may get a
Rental Locker as extra storage to prevent them from carrying the additional weight.
ShaKayla, I hope I've been transparent and helped you clearly see that you have bag options to help with your items. Please feel free to
write me back directly for other Disney vacation planning tips.
Enjoy making many Magical Memories.
