I wasn't actually talking about the Prince in that comment about getting the players loaded. I've actually watched it being done when someone was winning too much!
I believe the were several Casinos at the time and they were mostly associated with Hotels and "well connected," if you catch my drift. There were also still a very few of the older "original" casinos still left them.
As I recall, especially from seeing again something fairly recently, the city was segregated for quite awhile. Entertainers like Sammy David, Jr. had to actually say in the "colored" part of town, although he was allowed to perform with the rest of "the rat pack" gang in some of the "white's only" casinos/hotels. It's not a part of "the City which never sleeps" which is very frequently discussed.
I've never actually been there, and have little interest in going. I did,however, work in a casino at Lake Tahoe for awhile, while I was in College.
Regards,
