When we were there in 2004, they had just had a hurricane and were expecting one at the end of the week. They decided ahead of time they would close MCO on Friday at noon. Of course, our flight was scheduled for later that day. I spent the last evening of our trip on the phone with Airtran - we tried to get an earlier flight, but all were booked. The weren't opening the airport back up until Monday, so I rescheduled the flight for Monday. Then after I thought about it, school was starting on Tuesday, so we decided we would drive home (to NJ). We left Friday morning in the most beautiful weather (no sign of hurricane - they probably didn't need to close the airport that early!). Anyway, Airtran was nice enough to let us cancel our flights without penalty and gave us a credit that we used the following year. So, my advice would be to watch the news while you're down there and have a plan in case your flights do get cancelled. Good luck!
