Depends on what their interested in....
I like remembering things from my childhood so my favorite is Pop.
If they like sports then do sports, music then do music, etc. The nice thing about the all stars is that you can walk to the others if you want to change the food court atmosphere. LOL They are farther away from the parks but has a McDonalds at the entrance.
Pop is right around the corner from Hollywood Studios. It has a lake/pond that has gators in it. (small ones but cool to see).
