We have stayed at one of the Epcot resorts a number of times and have had many breakfasts at Spoodles. It was never crowded, although we normally arrived at opening time.
It is a very nice and quiet way to start your day. We loved their breakfast pizza but they discontinued it a while back. As someone mentioned, they have changed their menu. I see a different version of their breakfast pizza/flatbread, but it is not the same one from a few years back.
The Yacht Club also has a nice restaurant for breakfast. It used to be the Yacht Club Galley, but I believe they have recently changed the name of the restaurant.
