Backpacking in Yellowstone Nat. Park? - yellowstone backpacking

I like to go one day to 12 hikers Yellowstone National Park next summer. I was wondering if you stuck a trip where I can make my own food, in bags to carry the night, stay in the park, and not just an Appalachian Trail. Anyone with information or links would be greatly appreciated. It would also be personal experiences or suggestions helpful.
