Andy,
It's probably been 15 years, but I played both courses at Fripp over several days and enjoyed each. The newer of the two, I believe, is one of Davis Love's earliest designs and it was pretty impressive. It wanders through some oaks and bleeds out into a marsh. It has a short par 4 within sight of the clubhouse that caught my pre-GCA-attuned eye as a nice little puzzle. The older course, back then, had a sandy, linksy sort of turf and ends at the beach. It's the windier of the two. I found both courses to be great fun.
