These poll results are very interesting... If I were
DVC and in a massive financial hole I would consider removing the restrictions knowing about a third of current owners would add on @ Riveria. If DVC did some marketing and better deals you could maybe gain another third of our owners adding on at Riveria. This could mean up to 66% would buy at Riveria without restrictions. Even if you say half the "Maybe" votes would buy thats 50% of current owners.
Removing the restrictions wouldn't cost DVC a dime which in today's market is amazing. Your expenses for removing the restrictions is zero and the sale through is in the 50% range of current owners. I know some will say they are playing the long game but right now we are seeing unprecedented times. Let hope DVC reads this thread!
