While casino gambling is illegal on South Carolina soil, the Big M Casino sails out of nearby Little River six days a week, giving Grand Strand visitors and locals the opportunity to legally gamble in a fun and adventurous environment.ĭeparting from its docking station on the Little River waterfront, the massive, 186-foot yacht heads out to the high seas for approximately five hours of gaming fun and sightseeing. Guests at North Beach Plantation have a limited number of options when it comes to casino-style gambling: You can travel thousands of miles west to Las Vegas, hundreds of miles north to Atlantic City, or just three miles offshore into international waters.
