Lakewood RV Resort at exit 53 on I-26, Flat Rock, is a few miles south of Ashville. We stayed there several days while looking around for property. It is a convenient and an easy in, easy out less than 1/2 mile off the interstate.
If you can afford the time, you may wish to stay longer in the area. In Asheville, the Biltmore is a must see place if you have not already. If you have, it is well worth seeing again because they are always making improvements. Recommend lunch or dinner at the Deer Park Inn on the Biltmore grounds. The Winery produces a very good wine - to my untrained palate. You can check them out at http://www.biltmore.com/
. Biltmore Village, just outside of the Biltmore property is a very fine place to shop & shop & shop. Lunch at the Train Depot is a very nice break.
A stroll through downtown Hendersonville can eat up at least an afternoon. All kinds of little shops and wonderful place to eat.
Hubby could probably find enough in the Lake Lure to keep himself busy if he doesn't want to tour & shop with you.
Unless they have done a lot of construction in the past year, I-26 can get pretty rough south of Ashville.
Suggest you watch your speed. State troopers in that area have no sense of humor.
