What about Glow Sticks, Clow bracelets/neckaces, Disney light spinny thingies (about $15 in the parks!

I got them from the Disney Store for $2 on sale!), Disney PJ Pals (cheap right now at DisneyShopping!), Disney Swim Suits and towels (if swimming is on your itinerary...they are sooo cheap right now at Disney Shopping!), Disney tee shirts, Disney coloring books, a box of crayons, etc. I could probably go on and on!!!!!!
