My DF and his wife 5th wheel about 10 months out of the year. When I get them gift certificates it's usually Cracker Barrel for him and SpaFinders for her. That way she gets a nice treat even if they are on the road, she just looks up the closest spa to wherever they are on the internet. They love Cracker Barrel as it is one of the places RVer's can stay overnight if need be. They can also rent the books on tape there for the road if there is something they want to hear.
