The status here (in Las Vegas) has always been up to what policy each company wishes to have. The casino/resort policies have always been pretty much universal that no unauthorized weapons are allowed anywhere on their private property. If they become aware of a weapon, they will ask you to take it to a vehicle outside, perhaps your room safe if you're a guest of that property, or for certain individuals will store it in the security office during the event that the person is attending (this probably will no longer happen with everyone more on edge now). So if you don't tell anyone and nobody notices, you'll get away with having it on you or in your room. If they find out, you'll be asked to leave if you can't/don't wish to store it somewhere while on the property. Legally, I don't think there's any issue except that they would trespass you if necessary. I don't think there's any law that protects a right to carry on private property (but in public yes, with appropriate licensing for concealed).
