The $20 buys you an entree platter and dessert anytime you like, all day, at participating restaurants. You can go back through the lines and get as many entree platters and desserts as you want. There are six or seven participating restaurants and all are inside the parks. All appear to be "fast food" counter service. Looks like it doesn't include drinks, there's apparently a mug deal you can buy separately. No separate snacks. And they don't permit sharing.
