My husband and I take "mini vacations" several times a year, rent a cabin and enjoy the scenery and time with each other. One area we love is Highlands/Cashiers, N.C. in the Smoky Mountains. It takes about 2 1/2 hours to drive there, and there are great trails to walk/hike and great restaurants.
We have also used "Vacation Rentals By Owner" (a website) to preview the cabin, availability, pricing, etc. and book directly with the owner(s). The benefit is that we've been able to ask any questions that were important.
Congratulations on your anniversary, and have a wonderful time together!
