You never know, twice now we have been lucky. Way back in what 94 or 95, can't remember we were walking down the path to jungle cruise and was asked if we would like to test Indian jones, they wanted to see if a blind individual would have trouble in the room with the movie, someone had said they would. Sure enough that is the hardest room of any in DL for me to get through. So we went on probably two weeks before it opened to the public, with several staff members.
Then when we went in 2006 I think when the Nemo sub opened, we where there for several days before the ride opened, we entered many ap and other contest but never won, so we just hoped. Then one night while walking to the monorail, a cast member handed us a pass to go on, we had no wait and just walked right on. When it did open a few days later and for over a year we could not get near it so we were so happy to have won twice, especially the two rides that had the longest wait lines, if anyone can remember the Indy ride had wait lines or four and more hours at one point after they opened.
