Samantha,
I've been packing some stuff for months! I have a box (diaper case size) where I pack stuff for the trip. I have glow sticks, pins for trading, ponchos, autograph book, Disney character t-shirts, sunscreen, Disney stickers & tattoos, Brita fill & go bottles, soft sided cooler, clothespins, ziploc bags (you know, the stuff you don't use everyday & don't want to forget). Whenever I come across something for the trip I throw it in the box if it is not clothing we'll be wearing! Now that summer is ending you can probably pack up the summer outfits you are bringing (unless you live in warm weather year round!). I am going to keep my Disney box accessible ALL THE TIME because hopefully we'll keep piggybacking Disney trip after Disney trip!!!!
