My friend was telling me about Ace Hotels, which I feel is fertile ground for a Carcosa/Ruin type series.
The idea is that the company buys up historic buildings with a lot of character as hotels that "appeal to the creative class." Often they're buildings with an odd history that must be restored or adapted into hotels. They often have restaurants and entertainment worked in and an emphasis on community among the guests.

From the website:
We believe that Mr. Strummer was right when he sang, "If you're after getting the honey, hey — then you don't go killing all the bees," because there is no honey without bees.
which is delightful if you've listened to the Night Clerk.
One of the owners died suddenly in 2013, so if you don't feel too ghoulish working in real world events, that is also an option.

The fact that these are all owned by a corporation that keeps adding to its portfolio immediately adds a sense of conspiracy. Are all the hotels connected to Carcosa? To each other? Are they anchoring their respective cities into Carcosa?
I could see a similar idea working in Ruin with a less flashy hotel chain. Are those hotels by the side of the highway so homogeneous that you can enter one and find yourself in a different one? Or when one really goes wrong, can that infection spread through the whole chain?
Still on the note of hotels: the Illuminati room in the Hotel Zaza in Texas.

Ken and Robin have talked about it as well:
