BBB @ MK is usually always running late, not sure what time their first appt is but I've never gotten in on time at that location; only at Disney Springs. Her total time will depend on how fast they take her back, how fast her godmother is and how long her hair is. Sometimes they have two godmothers working on one girl and sometimes they don't, it's been as short as 45 min for my one daughter and as long as an hour and half when they were delayed. I think the breakfast time is cutting it close IMO. If she arrives already in her gown, that will save time but if you buy the Parks gown and her her do a try on, that will also add time.
