I have a couple of things to add...
If you're going through the candy lines and don't have a bag, the CMs will give you one...even if you say that you don't want one. I got tired of carrying mine and was planning on sharing my then-boyfriend's candy...but every time I would go through a line, someone would hand me a bag!
Also, DRESS UP! You get so much attention from the characters...even the ones in the parade, when you are dressed like a Disney character. We had awesome Alice, Mad Hatter, and Queen of Hearts costumes and we had characters pointing and waving, and even had Jasmine and Alladin say "Alice! What are you doing here? Shouldn't you be in Wonderland?!" While they were dancing by us!! It makes the experience super magical.
