Just my 2 cents ....
I think something like this, either points-for-perks or so many free tickets with certain bookings (2 free tickets for 1 week at a 2BR, etc) would be a huge incentive, both to DVC prospects and existing members.
Honestly, the one thing that really held me back from joining DVC for so long was the fact that I would still be paying for park tickets. If it was part of the "package" I would have joined 10 years ago.
It is something that is always a surprise to "outsiders" who ask about our reasons for joining DVC. It is almost always their first assumption, that you get park tickets as part of the deal.
I realize DVC isn't hurting for new members, but it would make the whole prospecting experience a slam dunk. I can rent out unused points and get the same result but I would prefer to have some kind of "in network" option to make it more seamless.
