For all his verbosity that was something I've wondered about from the time I heard that 8-12 guns had been found in his room. Now we know it was about 20 long guns plus 2 or 3 handguns. Add in God knows how many thousands of rounds of ammo, and yeah. Even done over 3 or 4 days, just how in Hades did he manage to bring in so much bulky and heavy stuff without getting any attention from hotel security? Nor catch the attention of housekeeping staff (even a couple of days of requesting no cleaning should have gotten some attention)?
I don't think so, SVP. Numerous and varying types of cases are common in Vegas due to the constant stream of trade shows. Would you pay any special attention to this?

How about this one?

Regarding the maid service - good point, but again, I don't think so. My wife and I spend A LOT of time in Vegas* and other casinos, we almost never get our room serviced during our stays. I also tend to see more room doors with "Do Not Disturb" placards in place than not, so we're not the only ones.
