Hi Sabrina! I see you will be visiting Walt Disney World Resort in a few short weeks! I'm sure you must be getting so excited!
This is a great question and I love how thorough you are being with your planning! I'm going to direct you to the
Walt Disney World Resort Park Rules for guidance.
As I'm sure you are aware, per Walt Disney World Resort Park Rules, "all persons, bags, parcels, clothing and other items may be subject to screening/security checks at the Park entrances and also within the Parks." The following items are prohibited:
1. Suitcases, coolers or backpacks, with or without wheels, larger than 24" long x 15" wide x 18" high (61cm x 38cm x 46cm).
2. Any trailer-like object that is pushed or towed by an Electronic Conveyance Vehicle, wheelchair or stroller, or pulled by a person, including wagons.
I hope this helps you with your planning. Please let me know if you need any other tips or have further questions regarding your rolling cart or backpack as you prepare for your magical Walt Disney World Resort vacation.
Thanks Sabrina!
Kari
