A couple of years ago I got 2 2br units at HHI and took my 4 brothers and 3 friends to golf at HHI. We did this in early November for a long weekend. We had a blast. The golf was great, although we decided not to play at Harbor Town because the fees were north of $200. We played two rounds at Palmeto Dunes (the Jones and Hills courses), 2 rounds at Palmeto Hall Plantation and the Davis Love and Arnold Palmer courses off of the island. The over all experience was great.
DVC has special rates with most of the courses in the area and as I recall the rates were all in the $100 to $125 range.
We used our OKW points and did our booking at 7 months. I'm not sure what the availability at HHI is, but if you are traveling and golfing in a lower traffic season the 7 month window should be pretty good.
DW has also used HHI for a "Ladies" trip. They stayed at HHI but not for golf. They used it for a base to visit and shop Savannah.
As far as WDW golf is concerned, the current DVC golf membership is a great deal. After the closing of OR and EP, there will still be 3 nice championship golf courses remainging (although I still hate the proximity of the race track to the golf courses for the noise polution). It remains to be seen if the closure puts an extreme pressure on the remaining courses or affects the discounts allowed. If the FS resort course is available to WDW guests to play, I would presume the fees would be much higher than the WDW rates. Only time will tell.
On the other hand, there are many Florida courses outside WDW property. Probably a dozen or so within a 10 to 15 mile radius. Not much different than HHI.
In conclusion, I would do as another on the thread suggested and try HHI to see if it is somewhere you would go regularly or if it would make more sense to do more at SSR or AKV and just use the points for the 7 month window at HHI as needed.
