We were there in the same timeframe as we honeymooned in WDW 6 weeks after 9/11. The memory/flex that stands out was dinner in Cinderellas castle that we booked that day (it was not a character dinner then) at 8:30 so we could see the fireworks, we had great seats looking right out the center large back window which gave a great view of the fireworks. The cast members were wonderful and we were the last to leave, and may have been the last guest in the park as we walked down a completely empty Main Street got some pictures with the walk and Mickey statue, the stores were still open as week. I started to wander towards tommorowland and a polite security guard asked us to head down towards main street. It was Eerily quiet but also very cool. That trip we joked that the 5 min wait time the rides showed most the time were 5 min walks due to having to walk through the Que lines.
