Tennis Resorts South Carolina

Rentals 1500-2000 km from Ontario, Toronto?
My parents are planning to go on a road trip to take leave and blah blah blah work I looked in Florida, but their complaints about the way it is. They watched stations in Myrtle Beach, South Carolina, but there is not much, it seems like an ideal place for people who are in sports such as golf, tennis, etc. Arnt. Suggestions? background on them is that they are in their years 60 that they like to lie down, relax and lover of food, and culture.
They can enjoy a drive to Virginia to Toronto. Colonial Beach is a nice to take a vacation. There are over 20 different restaurants, including a Thai restaurant that opens early. I am very excited this subject.
