For DVC members, there's a DVC Golf Membership for about $90/year including tax. You pay for the membership at a golf clubhouse.
For this membership, you get to bring up to three guests for a significant discount....enough that if you take 3 guests you'll save money even if you only golf once.
For our trip, reservations are 90 days in advance...for some reason I think early January it's only 14 days.
For example, I'm taking my father-in-law, brother-in-law, and sister-in-law's new bf with us in December. Regular green's fees would be $436+ tax. With this membership, we're paying $90 plus $53pp (tax included), or $290.00 and I'm probably going to go with my f-in-l again if we can schedule it.
Of course, there's the initial $12K plus annual maintenance fees to join DVC, but if you're already a member who likes to golf, this is a pretty good deal.
Hope this helps (at least some people),
Joe
