You sure can. We stayed at All Stars. You park as if you are going to Hoop De Doo or River Country. Catch one of the inside buses, and get dr opped off at the Meadow. We got there about 7:30, and did a little shopping first. We bought our s'more stuff (with sticks)at the tading post, although you can also buy marshmellos and snacks at the snack bar at the campfire. They have a nice little fire for cooking your stuff..although I'm surprised at how little attention some of the parents were paying as their children swung aroudn the burning marshmellows. We started to feel like babysitters.
Chip and Dale signed autographs, and they had a nice sing along with a guitar playing gal. They called the kids with birthdays up, and my grandson told her that his was the seek before and they invited him up. He was pleased as punch.
We didnt' stay for the movie, but caught another bus for pizza up at the restaurant, and went to the beach to watch the light parade. Took a bus back to our car.
