We had all 3 of the kids take their pics with the characters at the same time, simply because there were always so many people behind us waiting in line. I had to admit it did get on my nerves one day at Character Connection, when we were in line behind a family--also with 3 kids--who had to get every photo configuration possible (whole family together, then just kids, then each kid individual,then Mom with kids, etc.).
Plus my kids were always so eager to move on to the next character I don't think we could've done individual shots even if we wanted too!
We didn't do any "entire family" shots; next time I think we'll do that a couple of times instead of just the kids in the pic (providing the CM is willing to take the picture)
