Was just down in myrtle a couple of weeks ago, very disappointing pinball scene. Even the Ripley's arcade didn't have a Ripley's believe it or not pinball. How could they not have one!?!
The line of pitch and bats were fun to play and great to see a line of 30 identical machines, as you don't see that in arcades anymore.

A couple of general Myrtle beach suggestions,
-House of Blues, Sunday morning gospel brunch buffet. Live soulful gospel music, great buffet with biscuits and gravy, and chicken and waffles....need I say more?
-Murrells Inlet, Amazing brackish water area that is lined with bars and restaurants, dock that connects all the bars, live music at almost every place, you can buy a drink at one bar, walk down the dock 6 bars down and drop your dink off there and get another. Great seafood! We found this area toward the end of our trip and if we had found it earlier we would have spend every evening doing dinner there. Fantastic selection of food from very inexpensive, to very expensive.
