If the economics make sense ( and most people come up with DVC "breaking even" between 7 and 12 years of use) why does Disney have to "justify" the fact the price is higher now than it was in the past. Room charges are higher than they were 10 years ago, does that mean Disney allows you to check out at 16.00 to compensate for the extra cost? It was a bargain when it was first sold and IMHO it still is now. Disney has one Timeshare interest, IF it wants to sell it in the future it will be much easier to do so as a single unit. Disney sells DVC because of the flexibility of the system, having two different systems opperating at the same time means people will feel there is the possibility the freedom of movement between the two MIGHT be changed at some time in the future. IMHO that weakens sales for VEP because , as has previously been noted, VEP will be similar in feel to OKW ( a stand alone DVC resort not walking distance to a park). While I prefer OKW myself, there are times it suits my party to stay at BW ( or BCV when open). People may prefer to buy a resale (with the choice of 6 different resorts) over a longer term but just ( at the moment) one resort.
If fact I think that's an interesting idea an I'm going to poll it. Which would you prefer to buy IF ( and I don't think it would happen because I think I know the answer) there was a DVC 1 and a DVC 2 . given the choices are
DVC 1. 38 years of OKW, BWV, BCV, VWL, HH and Vero.
DVC 2 50 years of EPV ( no guarantee of whatever switching facility to continue, the site will be under construction for at least the first 6 years, no new beach resorts)
Given that by the very fact EPV would be a "new DVC" how could anyone buying be confident that IF Disney built more DVC resorts they wouldn't just make each new resort a "stand alone" entity. You could end up with very little opportunity to exchange into the "big six" DVC 1 resorts that would be able to out muscle the smaller entity in regards to deals done with II and the "concierge collection" hotels.
I think it would create more problems than it would solve for Disney and IMHO the more simplified a business plan is the more chance it has to succeed.
