We stayed in a little motel about 25 miles south of Paducah on highway 60. It wasn't a 5 start but it was comfortable and the was a diner a few blocks up toward Paducah that wqas great and very inexpensive.
Down town Paducah was great. There is a free parking lot about 5 blocks from the old convention center tthat we parked at each day. The suggestion to wear good shoes is a great one, you will do a lot of walking.
