Make sure you get around to all the buildings. The Toy Story courtyard is amazing as well as the Dalmations. There are many great photo spots in this resort.
As far as food, it's really no different than any other food court, but we found it good. Get refillable mugs, they make great souveniers as well as save money.
If there are separate busses to the 3 AS resorts and the line is shorter for ASMusic, you can take that bus and cut through the parking lot to ASMovies as long as you don't mind a 5-10 minute walk.
You can swim at ASMusic or Sports if you are staying at ASMovies, so if the pool is crowded, you can always go to Music. Music seemed quieter when we were there.
That's about it! Have a wonderful time!
