They won't have to do a thing to help direct sales at DLR DVC resort. Demand far surpasses supply. That is reflected in both the direct price of VGC and in the fact DVC has used ROFR on contracts as high as $186 per point.
You're assuming the price will be reasonable. I think they'll go all in, they know there are thousands of people waiting for another DVC at DLR. Price and points chart will be crazy. If owners will be able to buy one of SoCal passes even if not residents (like the Gold Pass), many more will find it a reason to justify the purchase.
