How far is downtown from I-81 and would you recommend staying downtown or near the mall. I am looking at Sheraton or Hotel Roanoke. Im just not sure if its downtown i really want to be sure or away from the congestion. Is the town easily walkable if we stay at Hotel Roanoke as far as shopping and going to restaurants with kids ages 7 & 9. Is it worth going downtown for just one night which is all we have as we will be going somewhere else the next day.
