From what I read elsewhere the "2 billionth customer" was a honorary title only. The 2 billionth person may have entered yesterday, but they randomly selected her family from the ticketing area prior to entering the park and pulled them backstage to sign the papers, then off to the ceremony at park opening. Her entire family got lifetime passes too, her parents plus her 6 brothers and sister (plus a baby brother/sister on the way) Not bad that Disney choose a family of 10 to give the passes to!!
