Report on ARFCOM where security found a guests handgun in a Wynn suite. Guest left their gun on the nightstand, went to dinner, then security confronted him and put the gun and ammo in their armory. Suspected the maid saw it when preparing the suite for the night, or it was detected at the entrance weapons detectors, or both.
No issues except having to retrieve it from the armory and being escorted out at the end of his stay.
Wynn has no weapons detectors at their entrances. No hotel does, on or off strip. Some do xray your luggage if left with the bell hop.
They also don't use facial recognition software for people about this, nor do they mark your reservation with the hotel. Or mark your RSVP for all future hotel stays.
I've had to check my firearm at various armories in Vegas hotels and they're really cool about it as it's no biggie. Each hotel also has their own SOP.
Venetian/Palazzo will escort you off property once you claim your gun from their armory. I was waiting for my ride to show up in the front of the lobby and the 2 guards were just hanging out with me. They didn't rush me to leave. They also weren't standing next to me, but like 10 feet behind me. I've stayed multiple times since and was never asked if I have a firearm when checking in, was never asked when giving my players card, or stopped. I even ran into the same security guard who escorted me off property 2 days prior and he never stopped to ask me about my firearm.
Planet Hollywood, I had to check my gun and remove the mag and clear the chamber. When I claimed it back, the manager there said I'm able to load and holster (IWB). Just do so pointing the firearm in a safe direction when loading and making ready. They didn't escort me out. I walked from the armory to the strip exit myself.
