My family vacationed there a few summers when I was younger. We'd stay at Jack Tar Village which now that I'm looking for a link to show, has apparently closed lol.
Don't have any experience since I haven't gone back as an adult, but from what I know if you want to drink it's a good place as you can walk around the streets with a beer in your hand and not get hassled, and if you're looking for touristy stuff to do there's plenty of that as well.
Climb Dunn's River Falls.
