We go to Ocean Lakes but it will be more crowded this year / summer. They are to open a new 2 Acre water park, They have a big arcade, a small putt putt but there are many great Putt Putts in the Myrtle Beach area we like Mt Atlanticus the best. Pools and almost a mile of beach. Most of the ocean front sites are small and a golf cart to get around is almost a must. Many sites have concrete pads which helps keep sand to a minimum in the camper.
But it is the biggest campground on the East Coast 850 Campsites and 2500 plus permanent site and can be crowded. They have 450 employees in the summer months. If you don't like crowds it might not be for you.
We have been going to Myrtle Beach for 20 plus years and it changes annually...
