I will say that I often travel in the off season, and at Dinner at Epcot I have had the experience of not being able to get in at any of the places I tried (Morocco, China, and the Italian place) ...it's weird to be in Epcot and STARVING!
Now , I try to have a priority seating somewhere. The Sunshine Season Food Court in the land is good though and realitively less expensive and it is counter service.
