Sometimes it is one or two characters, sometimes it is 5 or 6 or somewhere in between. If it is just autographs, 5 or 6 characters sit at a long table and the kids go in one line from character to character. Other times, there will be characters in different "corners" of the lobby for pictures. You can also get an autograph from character who are there for pictures. I found that the lines moved very quickly. The characters also sign autographs during the character breakfast.
