I've done it twice and absolutely love it. Even did it on Halloween night last year!
The walk way from Toon Town to TomorrowLand, ya know the walk way that you only take when the park is crowded and you want to get there fast, anyway, make sure you walk that path. I saw characters from Alice and Wonderland, that I had not seen on the park before! I met the Walrus, I met the 3 of diamonds, the 5 of spades, and the Queen herself! If you want to walk through fast, just walk past the characters and hit the candy stops. Real quick. You want to walk through slow, visit the characters also.
Have a great time!!!!!
