Maybe they could take over Circus Circus (and The AdventureDome).
I was thinking more of the WB resort/casino being a newly built property.
The Peppermill...My family stayed there once when I was a kid.
) For a Vegas location, I honestly think Buffalo Bill's would be perfect. It's already a legendary roadside attraction that's trying to make strides towards reopening their hyper coaster. At any rate, having recently just watched Looney Tunes: Back in Action for the first time I sort of fell in love with Yosemite Sam's casino design and could totally see it being incorporated into a Vegas setting. WB is definitely a solid IP to work with as the only theme park connect they really have is Six Flags, so doing something that's not technically in a park could ironically open up a bigger budget for them.

Maybe in the right have Ruby Rose as a showgirl?
If you would like me to, sure. The hotel/casino building would have a giant WB shield on the front, as well as a replica of the WB water tower near said building. The indoor WB park would at least have the rides, attractions, etc. from Warner Bros World in Dubai, if not some or most created only for the Las Vegas park. Those original attractions could be inspired by WB/New Line/pre-1986 MGM films like Wizard of Oz, The Matrix, the Middle Earth saga, Gremlins, Inception, etc. Any other suggestions?
RWBY is an obvious pick you’re missing. Inception might be too cerebral.
