Movies is great. It's a good sized resort, too, not too big, not too small. We were in the Mighty Ducks building, and had to walk every day to the Cinema Hall to get the busses, and it was a very quick, nice walk. Much smaller than Pop Century, I think. (Pop's great too!)
Definatley invest in the refillable mugs, especially if you will be bussing it to the parks!
Have fun!
