We have generally had positive experiences with late seatings at Character Breakfasts and have enjoyed extra attention from the characters as well as a less hectic atmosphere. However, our experience at Chef Mickey's a few years ago was not one of them. The food was plentiful and we saw each of the characters, but we were off in an enclosed area. A lot of the other diners in that area finished their meals and left just as we were getting started. We did see all the characters, so I really can't complain. But had we been seated on the main floor along with the other late eaters, the experience would have been much better as that is where the characters focused their attention. And, yes, we witnessed them visiting other tables multiple times. It was hard for our then preschoolers to understand why Mickey, MInnie, etc. didn't come and visit them as many times....
One of the more recent character breakfasts we enjoyed with a late seating is the one they have at Ohanas. The children were invited to get up and parade behind their favorite character, Mickey.
