Nothing like having a decision made for you!

But honestly, sometimes it takes the stress away.
We haven't stayed at the Fredericksburg KOA, but we've stayed twice at Jacksonville North and we really like it for the final night before WDW. The only thing I don't like about it is that since it is so close to the border my DH never wants to stop at the FL welcome center for the free juice since we've just gotten on the road!
Safe travels!
