We stayed at the ASMu in 2001 and loved it. The rooms aren't very big, but we didn't spend much time in the room, so it didn't bother us. We had myself, hubby, and two teenage boys. I found the resort to be very clean and the grounds were fun to look at. We stayed in one of the Broadway buildings, so it was a little bit farther to walk to the food court, but I enjoyed the walk and looking at the scenery and the pool.
We got a great deal on the room ($59/night) through a code on mousesavers.com.
The food court offered a wide variety of food choices, and it didn't taste too bad either. I always worry that food from places like that won't have much flavor, but it was good.
All in all our experience was a good one. If you have worries, just put them aside and take a chance. Especially if you have children. Children really love the All Star Resorts. They are so whimsical and entertaining.
Good luck, hope this helps.
