We went to DW in August 2004, everything was paid for in advance. The day we drove down, Hurricane Charlie was about to hit Tampa. We decided to go anyway. As we drove down into FL, the opposite side of the interstate was jam packed with people evacuating. We arrived at our house in Kissimmee 4 hours before Charlie went over Orlando, I think it was a category 2 or 3 at that time. It was my first experience in a hurricane. We were due at MK the next day.
Our electricity went out and it was muggy but bearable. The next day we were finally able to see the devastation. It was like a war zone as we drove to MK. People were lined up for a half a mile or more at gas stations, there was no where to eat but Waffle House, it was surreal.
Upon entering MK that day, it was empty. I mean like....EMPTY. It was the best day I have ever had at MK in all my visits there and I would do it again in a heartbeat.
We were without power for 4 days so it wasn't all fun but we managed with a grill and some candles. Still, even at that, I'd trade it again for the awesomeness that was being able to pretty much have the MK to ourselves (obviously there were other people visiting but it was incredibly low crowds, no lines for anything). AK was the same way the next day.
I'm not advising for anyone to ever do this. Just wanted to share that for us, it was an incredibly memorable vacation.
