When we were there last April (2007) we had gotten FPs for Buzz on our last day in the park. When we went back to ride, there were no lines for anything, Buzz, SM, Autopia, Star Tours, because 1/2 off the park (NOS, CC, FL, and AL were closed for a private party, it started to have a lite drizzle out, so the rest of the park was virtually empty (almost like winning an extra hour, but make it 2-3 extra hours). I showed the CM our FP at Buzz, and he said to save them and use them later, I told him we were getting ready to leave and it was our last day, he said "Save them for your next trip", we sure did, and had no problem. That was 6 months later!!
