I toured a couple distilleries in the Lexington / Frankfort area and really enjoyed it. I can't speak to your other options, but I think you would enjoy the offerings in Lexington. Beautiful part of Kentucky as well.
I went to Buffalo Trace almost a decade ago and really enjoyed the tour and the tasting room. You could buy a couple of things that they don't have in stores. I got a Christmas bourbon cream that was delicious. I have also been to Makers Mark but got there too late to do the tour. Makers Mark is in a pretty rural location while Buffalo Trace is right in Frankfort. There was also a great liquor store in downtown Frankfort IIRC that had a crazy number of different bourbons, which was a revelation to someone who has to live with the limited offering of NC ABC stores. I also toured Woodford Reserve in Versailles, KY and that was delightful as well. What sticks with me after a decade is that this is a centuries old art and it was neat to learn about it and sample the offerings. It was a while back so I'm sure things are even better now.
Enjoy!
