It’s not so much as how he got it up there but that no one seemed to be suspicious of that much luggage - and he’s wasn’t even a woman!
What did the cleaning ladies think of 42 suitcases for one guest? Probably the “what happens in Vegas, stays in Vegas” attitude. Hopefully, it’s right in this case.
Maybe because he was staying there for like 5 or 6 days before the shooting? They probably thought he needed the stuff for his week stay. Maybe they thought he was going to stay even longer? Remember this is a guy all the hotel casinos knew and have known for years not just a couple days but for years
why would they suspect him of anything nefarious?
I've checked into hotels with two or three full luggage carts full of jobsite equipment (mostly electronics) and have never once been questioned by hotel staff. I'm also seen radio/tv people check in with tons of AV equipment and never questioned. This hasn't been on the radar... until now.
