Nightlife near Myrtle Beach Resort

My husband and I are spending a week at the Myrtle Beach Resort 5/17-5/23 to celebrate our 20th wedding anniversary and would like to find someplace to go dancing one night. We're in our 50's and not interested in the meat market atmosphere just a nice tavern with some good tunes, maybe a decent happy hour, etc. We live in a VERY small town and do better in smaller friendly venues. Any suggestions are welcomed!
