Sure there's a line they could cross over that will hurt the company and hurt the product. However, I feel the location of that line is far different than many here do. I believe one has to separate out the hype and sales process from the product in large part. I believe they're a lot DVD can do to hurt those with unqualified points that hasn't been done and would still be appropriate. As long as they stick to the contractual obligation and run the resorts fairly well, I doubt it'll be an issue. With any change there will be losers but usually winners as well and some of those losers will vote with the $$$ but unless the numbers are enough to hurt DVD or such changes actually give Disney a black eye, it won't matter. There are also a LOT of things they could do differently in the sales process that would increase their sales numbers and many of these would still be appropriate and professional. I'm sure there's a tipping point but overall I think DVC members and potential members have proven their sheep being led to slaughter, happily and willingly.
I know you're being sarcastic but in reality your statement isn't that far off from how many have looked at DVC going in and how unrealistic many were (still are) in their approach and expectations. Here's one example that's fairly broad related to then current members. A few years ago the valet parking contract was up. Historically it was done by Disney then it was contracted out. During the entire preceding time, DVC members at DVC resorts were allowed to valet park for free. With the contract being up for renewal, the valet company wasn't willing to continue it as an add on just to have the business and apparently weren't willing to discount it. So DVCMC was faced with the options of terminating the perk or paying full price for each member. Clearly there was only ONE reasonable option, terminate the free valet parking, which they did but did poorly BTW. You may want to go back and find that main thread if you have an hour to kill. I am just amazed that some really felt the other members should pay for their free valet parking.
