Donald, Mickey, Minnie, and Goofy are all at Cape May for breakfast as I recall, and it is a great breakfast, and the interaction is very good as well.
Mickey, Lilo, Stitch, and Pluto are all at Ohana's for breakfast.. again, food is very good and interaction is good as well.
Just a quick correction...Mickey is not at Cape May. Cape May consists of Donald, Goofy and Minnie. Have eaten there many times, most recently in March, and it has always been the same characters. It is very cute...a beach/surfing theme.
