I don't blame you for being upset. Just don't expect you voicing your opinion to change a thing. The hundreds of people that you speak to do not come close to comparing to the amount of guaranteed customers they just got. I just bought into DVC this past summer. I am most definately not thrilled, but I understand why they would do this. The best thing to do is to first off just relax about it. It may only add 100 or so fastpasses per day, if even that. If traffic shifts from the on-site hotels to these, and then those on site rooms do not sell, nothing is lost in terms of fastpasses. I highly doubt a ton of people will want to pay $170 a night to stay off property, just for the fastpasses. Some, sure, but most will find it not worth the hassle.
Even if things do drastically change fastpasses, this is where being a DVC member is so nice. Just slow your trips down and do less rides in a day. There is so much else to do in the parks, it should not be too big of an issue with all of the new E-Ticket rides being added over the next few years.
If Disney does find that this negatively affects them too badly, I am sure that they will pull this perk back.
