I had the same experience as previous poster at breakfast at POR. We went the last week of August/1st week of Sept when Disney, as a whole, was not that crowded. However, POR was packed in the morning. We actually ended up eating at the sit down restaurant, which they do allow overflow so that was good, but I kept getting banged into at breakfast.
We ate lunch there once and it was SO empty and the food was great! I am gluten free and got the pasta station. They were wonderful with me!
