The Hampton Inn in Clarksville is fine although the off highway location is hard to find and even harder to get back on the highway. You have to jog over two blocks to hit a light on the main road so you can turn in the right direction. Ask at the desk, the staff is very helpful.
I originally booked this room for $89 through the Hilton/Hampton website, then decided to look into their Lowest Price Guarantee. I found a $73 rate and booked it, then called the hotel to cancel the previous booking. The manager pointed out that this was a military rate, so read the fine print. He did find an $80 rate for me, but I am still having trouble collecting the guarantee from Hilton. Do not believe Hilton, come straight to Discounthotels.
