Now that Steve has ruined the thread by giving out actual information (just kidding!

Thanks, Steve!), here's another FP story.
One day last month at MGM we wanted to go to Millionaire, but there was a long line waiting to get in. Not nearly long enough to fill the theater, just long enough to bum us out. (We hate waiting in long lines.)
So we decided to grab FP's and go on Backlot Tour first. As we passed the FP entrance to Millionaire I still had the FP's in my hand, about to put them away. A CM at the FP entrance shouted "come on in!". I explained to her that we had just got them and would come back. She told us to "come on in anyway" and we didn't even have to give our FP's!
We couldn't pass up that offer, so we went in, and I mentioned to her that "there ARE a lot of people waiting in line back there". As we entered the theater I looked back to see her telling another CM , "He says there's a line out there!"
We used our FP's on the next show. Neither show filled the theater, so it was all in good fun.
