We had an amazing time in Folly Beach thanks to our stay in Mariners Cay. The site is top notch; you don't have to worry about insane beach parking or driving back and forth, because you can keep your car at the condo and walk across the bridge. Easy peasy. Spectacular Folly River views, too.
The unit itself is everything you need; good size (2 bed, living, dining, full kitchen) - and we were spoiled by having 2 bathrooms too. Property management is very, very considerate - with some starter amenities, good housekeeping, and not at all stingy with the bath linens.
But the piece de resistance that every unit has is the screened in porch. Mariners Cay made us decide that we will never, ever, for the rest of our lives, be without a screen porch again. Period.
Having a dinner guest, someone to come pick you up, or pizza delivery is a minor pain, though. No gate code means you have to run out to the guard gate every time with your passcard.
