I would probably recommend a caddie for all of the courses at Sea Island. If you can afford it and and you can schedule it in advance, I would always recommend a caddie. I booked this round last minute and really didn't have it in the budget to take a caddie, but when I go back to the Seaside course, I will most likely take a caddie. Putting on greens of this quality without a caddie is like being lost without a map haha.
I've never heard of that course but just looked it up! That looks like an incredible course! Will definitely make an effort to get on there if I am ever down in that area!
