Chattanooga is a very nice area. My suggestion (and what we just did in June) is to pick up the hotel coupon books at the Tennessee Welcome Center/Rest Area and then find your best rate/favorite hotel in their. This seems to be what I have found to give you the best rates. Be aware that some aren't available on weekends or have different prices listed for Fri and/or Sat, but still usually a better deal than rack rate from the hotel.
