We are definitely all spoiled since the advent of FastPass. Last time we were there, my wife (who's first trip to WDW was in 2003) refused to wait in line for Space Mountain for 35 minutes.
I can remember when I was a kid, we waited in line for Space Mountain for a good hour and a half, and when we finally got out of the tunnel and into the building, they had to shut the ride down because of a problem on the track. We waited for another 1/2 an hour (while they turned on the lights in the buildling--yes, I've seen Space Mountain NAKED!) before they eventually told us they had to close down the ride for the night until they could fix it. Talk about a letdown.
