I have also found the small boxes of white or choc. milk(about the size of a regular juice box) for a dollar a piece at our local Dollar Tree. This would come in handy if you were going to eat cereal in your room before hitting the parks. Walmart also carries it is a large box of groups of 3. Last summer that had great hats that my DD9 and her friends loved! You can buy bandanas there too! Lots of Disney stickers, pens, coloring books, crayons, etc. I just bought two to a pack Mickey Mouse card games-Go Fish, and Swap. If you take your time and look around it's amazing what you can find. 
So what we do is we crack the door, drink our coffee outside and leave a disney bag on the door handle every morning. She gets so excited when she sees the bag because she never knows what will be inside. My mother likes to keep her eyes open for good things. Last year her ultimate present was a stuffed Duchess, this year, it's a Giselle barbie.
