We used to enjoy getting to the MK early and having breakfast buffet at the Crystal Palace. We'd get there early, get our food, grab a window seat and watch the crowds build up until the rope drop.
Not sure where or when the very first character breakast took place. It may have been at the Village Restaurant, and was part of a special perk for Eastern Airlines package guests. I know that in 1978, The Terrace Cafe in the Contemp offered a character breakfast every Sunday from 8:00 - 10:30. There were also characters at the Fort Wilderness campfire each night back then.
By 1982, they extended the hours at the Terrace to 8:00-11:00, and there was also a 9:00 daily character breakfast on the Empress Lilly riverboat at Walt Disney World Village. The Village Restaurant also had character breakfasts at 9:00 am. At the Poly, you could attend Minnie's Menehune Character Breakfast at 8:00 or 9:30 am. Price? ...$5.00 adults, 4.00 children. We still have our souvenir attendance certificates from that one! Sorry, I don't know how to post a pic of it here...
Also in 1982, the Golf Resort tried a new "Dinner a la Disney" in the Trophy Room at 5:00 pm. Adults... $12.00, children (12-18) ... $10.00. At those prices, no wonder character meals didn't catch on more quickly, huh?
