If you're heading to Epcot first thing in the morning, join the crowd and head to Soarin' for fast passes and/or a ride. Right next to Soarin' is Sunshine Seasons, one of the best counter services in all the parks! They have great breakfast options, including a few different breakfast plates- eggs, potatoes, french toast, bacon, etc...
Twice during my recent trip, we grabbed passes, took a first ride, then enjoyed breakfast!
