The closest movie theater is in Myrtle Beach, about 40 Minutes north.
As far as eating, there are the usual fast food places. Lands End is OK, the Ball and Que is OK, and Bills BBQ is good. If you want some good seafood for dinner, ride up to Murrells Inlet and check out 17 business. There are a bunch of places to choose from up there.
There is a carriage ride through Georgetown, but I have never ridden it.
Pawleys Island is the closest beach. Huntington Beach State Park is a little farther north on 17. Brookgreen Gardens is good if you are into flowers and statues.
If you have time to ride to Charleston, there is a bunch of historical stuff to do.
I don't know if you drink, but the few bars in town are pretty skanky.
The short story is, G-town is pretty low speed. If you want to do anything "cool" you are probably going to have to ride to Myrtle Beach.
