Isn't complaining about DVC akin to complaining about a new cruise ship being built? I'm not really seeing thread after thread that the Dream shouldn't have been built because the yeti isn't fixed. It's the same general department.
Or, if you want to put even a lesser point on it, complaining that ESPN shouldn't be renewing broadcast contracts because the parks are suffering?
DVC is an easy target because it is visibly associated with the resorts and only provides tangible benefits for DVC members, which do not make up a majority of Disney vacationers.
In the very long run, a DVC community with a vested interested in the quality and upkeep of WDW will benefit everyone. Especially if they become as vocal as the DL locals have become. For that to happen, DVC needs to make an even bigger impact on WDW's bottom line (in attendance).
To put this into perspective, imagine if 25% of the rooms available at anytime at WDW were DVC rooms and occupied fully (for the sake of argument) by DVC members. Just making up some more numbers, lets say this accounts for 15% of the daily attendance at the theme parks.
Furthering this scenario, lets say another fiasco like Lights of Winter happens and, given that the DVC community is just as connected as the DL community is, 10% of the DVC'er who booked canceled (because realistically, it's a vocal minority who will ever put their money where their mouth is). You are looking at a 2.5% drop in hotel bookings and a 1.5% drop in attendance during a holiday season. That's enough to make any company think twice about cutting their offerings.
People may not like DVC, and that is fine. It's not for everyone, but the potential that is there for it to be a driving force at WDW shouldn't be ignored. I'll be the first to admit that potential is a long way off, but it is there.
Once last thought, if the internet had been more prevalent in the early and mid-90s, I wonder what people would have thought about all the resorts that sprung up during those times?
