Disney's college program is great. Yes, you have to pay for your food and such while there, but they pay decent enough, and they provide a very good place to live. Vista Way is wonderful. Basically, you should bring enough for souvenirs and booze. The Walgreens outside the front gate of Vista Way has good prices for the requisite alcohol. Also, look around for deals, your Disney cast member card gets you lots of discounts, both on and off property. And remember, always ask what you can get. I got free tickets to Medieval times from the nice ticket lady on International drive just by telling her I was with the college program.

Oh yeah, and if you can, have a car. Trust me on this. There's only so far the shuttle busses will go. Go shopping at the Wal-mart in Kissimmee, *VERY* good prices.
Other then that, just have fun, and kiss your free time goodbye!
