The Oak Barrel Tour Co.

We had a bachelor party booked with David from Oak Barrel Tours, and from what the Best Man has relayed, it could not have been easier or a more well rounded excursion. He took into account the crowd that would be there (about seven guys), the tastes that we had, and the plans before and afterward -- and made his suggestions likewise.
Oak Barrel was extremely accommodating in providing us an extremely comfortable transportation method, as well as locale based tips, tricks, and haunts, while we were at the destinations.
Breadth of knowledge of the area (and Bourbon) is something that is often overlooked while Googling the cheapest tour destinations and transportation; but if you trust Oak Barrel Tour Co. to take a role in both the transportation and the planning of your event -- whether that is a bachelor/ette party or a company retreat, or anything in between -- it's impossible not to have a great time for a great value. I cannot recommend Oak Barrel Tour Co. highly enough.
