Souvenir Tips and Tricks
A popular souvenir is the all-you-can-fit-in-a-box Disney-themed Mr. Potato Head toy. For a flat rate of $19 you get as many parts as you can manage to fit into the provided box, as long as it closes and is not bulging. This toy is available at many locations at Walt Disney World, including Mouse Gears in Epcot, County Bounty in Mickey's Toon Town Fair at Magic Kingdom, some resort gift shops, and Once Upon a Toy in Downtown Disney.
Here are some hints for getting the most for your money when buying this toy:
If possible, buy one or more basic Mr. Potato Heads while you're still at home. You can get one cheaply from a discount store (or even a thrift store or yard sale, if you're really frugal). The head sold at Disney World is the same as the standard ones sold elsewhere, and it's the bulkiest part. Since will take up a lot of room in the box, skip it and load up on the Disney-exclusive parts! You may be able to make up multiple complete sets if you buy the heads separately.
If you do buy the head at Disney World, be sure to open up the back and fill it up with parts! This is allowed.
Be sure to get plenty of arms at Disney World. The arms are different from the standard arms that you can get elsewhere, and they allow you to attach special Disney items like Mickey ice cream bars, video camera with Mickey ears, balloons, suitcases and autograph books.
The display at some of the stores allows you make your own Mr. Potato Head postcards. You choose the parts on a screen and then print the postcard out to take home. There is trivia on the back of the cards, and if you fill it out and take it to a sales clerk, they'll give you a certificate and a small prize.
