On the first day on Monsters Inc soft openings, my sister and I were so excited that we left our camera cases in the "taxi" on the ride at the same time. We realized it when we got off. The CM at the exit informed the inside CM's and they checked each car through one rotation and found my sisters case.
I checked lost and found a few hours later and low and behold...there mine was. It was nice to get my $10 camera case back!!
