We've been lucky enough to win a couple times. Twice we won ears back behind Dumbo, both were mornings about 9 AM. We won lanyards getting off Alice maybe 8:30ish. Both made us think we should hang around FL early, lol! Then the next trip we won lanyards in the afternoon in DCA going back through the arch thing to Monsters Inc (both Dream members were standing back against the arches, so still kinda out of the way). Then we won Dream Fastpasses down in Hungry Bear, so they were still out of the way. My bf saw all these people walking up from the exit messing with the lanyards, so we raced down! Woohoo!
Here's an interesting fact. We spoke to one dream member (not handing out prizes) and he asked us what was different about what he was wearing in comparison with what the members were wearing when we won. We didn't know. He told us it was the white vests. So if you see white vests, run for it!!
