I’ve long imagined that somebody could create a USS Enterprise (NCC-1701 series) hotel, underground. It could incorporate elements from several of the Enterprises on TV shows and movies.
First class rooms would be officer’s rooms, with less expensive crewman rooms. Part of the illusion would be that the ship was en route to a particular star system, with “arrivals” and “departures”, along with detours because of cosmic events.
Some elevators could act as elevators, and others as pseudo transporters, using different special effects.
There was a huge project that almost went forward to build a full-sized Enterprise in downtown Las Vegas. I read the article here in the last few months. They had the land deal in place, investors, the only thing that killed it was the head of the studio.
Here, I found the article.
