Comfortable shoes!!! There's A LOT of walking and when you're feet start hurting, you won't be a happy camper. You'll feel better in the heat with airy and comfortable clothes too
Extra socks lol they always get wet. I always bring a football or a basketball. We usually stay at the swan and dolphin and they have basketball courts. I also bring a football just to bring to the pool or around the hotel.
For the trip to Disneyland Paris (because USA is too expensive but it is my living dream) I put in my suitcase Disney t-shirts,Nightmare Before Christmas hoddie,converse chucks,Minnie Mouse ears,pin lanyard,towel,Disney Pyjama,French Duffy,Mickey pillow,other clothes for the trip to Paris,make-up,brush,money for souvenirs,mobile phone,my Annual Passport etc. And then we can start driving !
On the way there, the airplane, I bring a lot of stuff to play with. Even if I'm supposed to be sleeping. I bring games, my DS, and coloring books. I love to fly so I usually just look out the window.
To bring to Disney, I bring flip flops, and plenty of comfortable shirts and shoes. I bring my sunglasses and I bring my vinylmations and pins to trade while I'm there.
I always pack Disney t-shirts, socks, etc. especially my hats! Goofy, Jack Skellington, Mickey ears, all of those! I also take toys, stickers and such to decorate our hotel window and door.
I bring all of my Disney blankets! And my Imagineering book. I also have a list of things to look for in each park (push the talking trashcan, little things like that). I've been to Disney many times, and so I look for new things to do while I'm there.
My typical packing list:
-Mickey Mouse stuffed animal (I'm 16 but it's still a MUST)
-Phone & iPod with chargers, both wall & portable
-GUM
-Printed info sheets, Disney guides, Hidden Mickey books, & all other Disney information guides to get me pumped up on the way!
I also saw on another thread to bring power strips for the room & fast food take-out lids to put on ice cream & popsicle sticks to prevent messy drips!
