I'm excited for this! The A-frame cabins initially planned looked cool, too. I'm thinking Epcot or Animal Kingdom will be the next area to get DVC since MK is getting totally taken over by DVC at this point. If Lakeside Lodge opens 2027, whatever comes next is 2029ish, which dovetails with AK getting their big investment. Riviera will be totally sold out, unless they cannibalize another wing of Caribbean Beach and add on to it as Riviera 2.0. Hmm.
Animal Kingdom is unlikely, already has a huge DVC space, and it’s one of the less in demand.
I suspect Lakeside Lodge will take a while to sell. Likely a huge resort. So there may not be a rush for something new.
But I agree it’s likely that something would be planned for 2029.
I see 3 most likely locations:
1. Epcot area. Perhaps tear down Atlantic City Dance Hall and Jelly Rolls, build a tower there. Maybe build another resort next to Riviera.
2. A small expensive DVC hotel INSIDE Epcot. Been rumored before. Build behind the Land Pavillion.
3. DHS adjacent, maybe the land where the Star Wars hotel was built.
Next set of possible but less likely:
4. On the Seven Seas lagoon, between Contemporary and Poly. This has been a rumored development site since WDW was built.
5. Beyond Big Thunder Mountain: hotel with entrance to Villains land.
6. Like OKW or SSR, develop an unused part of the property that is not adjacent to parks. (Lots of land options, but such locations have proven less popular).
