We were there for Hurricane Jeanne (Sept. 25 - Oct. 2). Here's what happened with us...
We (DH, myself, DD-4 & DD-2) were scheduled to stay in a cabin at FW. On Fri. night we got a call from Disney saying that we could cancel/reschedule our trip with no penalties or be moved to a 1-bdrm villa at OKW. Since we were driving down & have lived through many hurricanes in LA, we opted to make the trip & stay at OKW. We could have postponed our trip by a few days but figured we'd get it either in FL or GA. So, we made sure we were ready to hit the road early Sat. morning. We arrived in FL at OKW at 2:30 on Sat. afternoon. We were confined to our room all day on Sun. Since we knew that we'd have a full kitchen, we brought frozen food & groceries from GA. We never lost power and were able to have our homecooked meals in our 1 bedroom villa. It really was nice to have separate room so that we were no couped up in a bedroom all day. I brought surprises to give to the girls throughout the week but wound up giving all of them to them that day. It surely did keep them from going stir crazy. On Mon., the parks were opened, the crowds were low and it wasn't very hot.
If you're worried about being confined to a room for a long period of time, either book something with a full kitchen or a deluxe where you can move about the resort indoors.
