I didn't hear of any golf perks. But DD and I used "last minute tee times" for some really good green fees at some wonderful golf courses last June. Check out their web site for details. http://www.lmteetimes.com/
Not really an actual "perk", but DVC does have "special rates" for members with some courses when booked through the front desk. Thing is, I have always been able to get the same or better rates directly at the course, or using coupons. Call HHI and get their rate sheet faxed to you, then call and/or go online to see what rates you can get on your own. Then check for coupons when you go in the various travel and golf guides. If going off-season, you will likely find something lower on your own.
