This is where you'll get to see giant stingrays, squirrelfish, snappers, tarpons and large sharks. In the Rio Amazon exhibit, you can see piranhas, the tiger shovelnose catfish and many other freshwater fish that live in the waters of the River Amazon.
Bowling is always a great indoor entertaining activity, and there are two venues in Myrtle Beach where you can spend an hour or two. Try out the Surfside Bowling Center & Brickhouse Lounge (no website: 510 Highway 17 N, Myrtle Beach; 843-238-9754) or alternatively the Waccamaw Bowling Lanes (waccamawbowling.com). Both venues have a snack bar and a lounge to relax in, and Surfside Bowling features host DJs and line dancing and salsa from time to time, and is well worth a visit.
The Children's Museum of South Carolina (cmsckids.org) is a great place to take the kids on a rainy day.

The Children's Museum is open daily from 9 a.m. until 3 p.m.
