Looking for suggestions on our 14 day trip to the southeast

It might be a little too far out of the way, but there are lots of Springs in central Florida that are incredible to kayak. Most have outfitters that rent kayaks, and have shuttle services.
Look up Rainbow River, it is 5 miles of water that is crystal clear. Icheetucknee springs is incredible, but not a long it big as rainbow. There are numerous others that I haven’t done, but look incredible.
