Take exit 59 off of I81, go left at the bottom of the entrance ramp onto Fort Henry Drive. The stadium is on Ft. Henry 6 miles or so from the interstate. This exit has a Holiday Inn Express. If you take exit 57 onto I181 to Kingsport, the second exit is Hwy 93 and it has a Hampton Inn, Jamison Inn, and a Marriott. If you are a golfer the Marriott has "Cattails at Meadowview", a resort course. The hotel has special rates that include the hotel plus a round of golf. The course is a nice one with some beautiful views on the back nine.
Have a good trip,
