Club rentals are available at all the courses, I believe it $45 for Cobras and $55 for titelist, $7 for shoes $6 for range balls.
DVC golf member greens fees for Aug. I believe are $35 but you have to play after 10am. You also get a pretty good rate with an annual pass, it's probably a little more than the DVC rate but you can get tee times earlier, but not as far in advance.
I usually play 2 or 3 times each trip, and I'm not very good either. My favorite course is LBV which would be very convient for you at SSR. I think it'a the easiest of the 5, and usually in great shape. I terms of difficulty I'd rate them as follows from hardest to easiest:
Magnolia, Oprey Ridge, Palm, Eagle Pines, LBV. Osprey, Eagle and LBV I think are the most scenic.
Last year they offered free club and shoe rental for DVC members I'm hoping the bring that back after the peak season which ends at the end of April.
Have a great trip and a better round of golf.
