Hi Mariajose, and welcome to planDisney!
I love that you and your family are in gear planning for your upcoming
Walt Disney World Resort vacation! When we prepare for our visit, I start that part of the planning process about two weeks before my arrival to ensure everything is in order and you are doing the same.
The
Property Rules, Policies & Regulations state that “Suitcases, bags, coolers or backpacks, with or without wheels, larger than 24” long x 15” wide x 18” high (61 cm x 38 cm x 46 cm) are not allowed in any theme park or water park.” This means it is permitted if what you described fits within the guidelines noted. In addition, if you plan to include ice in the bag, loose or dry ice is not permitted in the containers, but reusable ice packs are allowed. By the way, I love the idea of having a bag handy for your rain jackets because the weather can change instantly, so it is good to be prepared.
If you have any additional questions, we will be here if you need us.
Have a magical time!
Raquel
