In all my trips to WDW I have only seen families of 2 parents and 2 kids get to open the MK. You can only have a family of 4 to ride in the front of the Monorail. It seems like WDW likes it's "typical american family" of only 2 kids. In a recent post of a family who won family of the day it was again, only 2 kids. So do those of us with 3 or more ever stand a chance? Has anyone seen a big family win?
