My father owns a house in Myrtle Beach and I love going down there. As a kid we used to go every summer and it was the best, there is seriously nonstop fun down there. If your bored at night and your kids want something to do go over to Broadway at he Beach or Barefoot landing. During the day you can do things like going to the beach, going to Myrtle waves, the nascar cafe, or simple things like mini golf and the batting cages. Haha and food is not a problem over there, I think you and your kids would love it. And for a single mother like you I don't think it will be hard to find dates and men because there is also a lot of night life activity down there.
