Yea, just check when you get there, there will be signs up (or you can ask a cast member, although the signs are more reliable), that state if there is a fire ban in place.
It's been REALLY dry for us in the northern South Florida/ southern Central Florida area, so I can't imagine the Orlando area has had much rain either. In fact, most of South Florida and the Treasure Coast just went on water restrictions, that's how dry it is. I would probably think they have a fire ban in place right now, although once the thunderstorms start coming in daily (hopefully soon, we need the rain!), the bans will probably be lifted.
All the comfort stations will have postings on their message boards if a fire ban is in place, that's a good place to look.
