What trench?
There are a number of different interconnected issues with the Riviera DVC, so it's an interesting topic. Thanks for bringing it up! Have we discussed this aspect before in the thread? I've read the whole thing but don't remember a discussion of it's DVC attractiveness.
One aspect is that they simply need another DVC to sell and they're sort of running out of deluxe resorts to convert - though they could continue to convert more of the Poly or WL or build another BLT.
But I suspect that the main aspect is that they'd like to be able to sell a DVC connected to DHS when SW:GE opens. This is their best shot at that. I'm not sure if they could have built anything like it close to DHS without having sightline issues or water management issues or having to build a parking structure or where would they put a lake do they have to build a lake?
I do think that the issue of building a standalone DVC vs one attached to an existing resort and sharing infrastructure is one worth discussing. I remember but can't find a discussion of this, but I recall that the idea came up of Disney using "conversion" as a means of rightsizing their room inventory. So in this case Disney is "converting" a bunch of moderate price-point CBR rooms into higher end DVC Riviera rooms (offset by the addition of moderate price-point CSR rooms, but that may be related or unrelated). In doing so they get to share the Skyliner infrastructure, the lake, as well as probably some utility infrastructure. They also get to convert from the casual low-rise density to the currently more-popular covered, high-rise density that seems to have become more popular for some reason.
Some other factors to note:
1. Disney is getting rid of the "value/moderate/deluxe" categorization.
2. Everyone suspects that the prices will go up for CBR/AoA/Pop after the Skyliner starts running and SW:GE opens and they become more popular.
3. OKW and SSR are also at the old "deluxe" level and continue to be booked, and according to your criteria they have even less going for them.
I own at OKW but I'm not offended, don't worry! OKW has great balconies and spacious one and two bedrooms and great grand villas. They're huge if you're used to cramped NYC apartments. Finally, I can't wait for autonomous personal transit to become a reality so I can avoid the bus. I'm also looking forward to whatever the mysteriously rumored non-Skyliner transport replacement is for AKV and whether it will hit OKW/SSR/Disney Springs or CSR?
I think the trend will continue. If Riviera sells well, we'll see another DVC built somewhere on the shores of Barefoot Bay. My bet is just to the north of the new CBR Skyliner station. I think there will likely be another DVC somewhere else between the two - either the second BLT or the FW one, or maybe both?
