I was a golf professional in Hilton Head for 5yrs. Unfortunately, there are no casino's or card rooms to be found. I'm not positive, but I believe the Tradewinds cruise out of Savannah is out of business as well.
There was a legendary home game hosted by Michael Jordan at the course I worked at, but he has since sold his home.
Enjoy the hot weather and golfing!
I grew up in savannah. It is gonna be scorching in August.
Bring bug spray just in case.
No card rooms that I can recall. Wish I had a local game to get you into, but don't know if one.
