If you're looking for something different, the Plantation River Tours Waccamaw River Airboat tour is worth checking out. The ride is reasonably tame and not really a "thrill" ride, but it's a fun way to see a part of the Myrtle Beach area that most visitors never see. The boat is comfortable, and the captain is friendly and knowledgeable. My wife was worried about getting wet, but it's a very dry boat ride. Life jackets and hearing protection were provided.
We saw alligators, osprey and other river birds, as well as portions of old rice plantations. I never thought an airboat ride could be described as "peaceful", but the Waccamaw River is a beautiful place, and when the captain turned off the motor in some of the backwater areas, you couldn't hear any sounds except for birds. It was a very pleasant contrast to all the noise and activity in most of the Myrtle Beach attractions. At $40 each, the one hour ride is pricey, but there are discounts for kids, and there's really nothing else around Myrtle Beach that compares to it. I'd gladly recommend the tour to friends.
Tip: Scheduling your airboat tour to coincide with high tide in the vicinity of the marina will open up access to more of the flooded grassy areas and ricefields for the boat's captain. At lower tides, the boat is limited to the river and creek channels.
