I priced out a cash vacation during Christmas week at DH's urging, and we were stunned to see Values at $100.00/night (tax inclu) and Moderates $140.00/night (tax inclu) during Christmas. Deluxes were also on sale, but I can't remember all of the different price points. We were surprised to see many rooms available, and for good discounts. We are DVC, and don't buy cash rooms, so you may be correct with the discounts you've quoted, and would probably know better as you actually purchase cash rooms, but not sure for what time period you are quoting as you didn't mention dates?
Hmmm....?
I'm not sure what you mean by waiting 20mins to make dinner reservations? Are you talking about waiting in line at a restaurant in order to make ADRs? Waiting is very common - we have waited 1 hour to be seated for an ADR that we made 6 months prior. It all depends upon the guests, and with character meals, they linger way too long, so it makes for huge line-ups at check in. You will wait very long waits just to check in for ADRs at Chef Mickey's and 'Ohanah, and then wait equally (or longer) to be seated. Would love to know what you experienced with waiting to make reservations? Long line-ups, lack of staff, overcrowded restaurant, etc.
I will highly disagree about selling DVC at gas stations. I am a DVC member, and I don't want anyone selling memberships at gas stations.

It totally makes sense to sell at the actual resort - not sure why this doesn't make sense to you? If you don't want to go to a DVC desk, then don't. Seeing them shouldn't bother you, as they are small desks with signage attached. I'm not following you here...Selling at a gas station will highly devalue the membership that I spent $40,000 on. No thanks!
Ride issues have been happening for the past several years, on a consistent basis. We spend 2 weeks each summer, and the amount of rides that go down is very high. Now, you can say it's because of the big crowds, but since you are there during a not so busy time, and it's happening, I attribute it to maintenance issues, or lack thereof. Perfect weather most days, and rides broken down at all parks, is very common. We've had major portions of parks closed down (Tomorrowland) due to several rides that are closed. It's highly disruptive to crowd patterns. Add monorail issues, and you have major crowd issues.
