ALthough it didn't directly hit Orlando we were there for Hurricane Wilma. They closed the parks for the morning (we were told the night before) but then we got word that they would be opening around 2pm for resort guests only. What a day! The sun came out and the parks were empty! We walked on everything!
I do have to say we were quite scared the day before though. We got rushed out of EPCOT early as the CMs kept telling us they had to go prepare for the hurricane and in ESPN club the servers kept telling us they might make them stay overnight because workers might not be able to get there for work the next day and they had to have workers available. No one was in a good mood as all the CMs were worried about getting home to take care of their own homes. (couldn't blame them)
Also, the resorts were crazy the morning of the hurricane. Family's crowded the dining areas and arcades. People basically "set up" camp in the common areas.
