I haven't been there but I wish that I will go there someday but the best advice that I've heard about is that you should never get yourself get befriended by the locals because whatever they're doing to befriend you, they're most likely trying to hustle you, that's the only thing that I can think of when it comes to this kind of thing, another thing is the timesharing scammers there, don't give them the time of your day and they can take it up when you reject or ignore them, it's a scam that will waste your time in Vegas.
I don't really like judging people but I think I can give exception sometimes, especially on that place. Many people lose there and they are now finding ways on how to have a capital to go back playing again. I don't really get that Timesharing scammers you are telling but I guess they are like the ones who we talked about earlier, so the same measure we will apply and that is ignore every stranger we came across or trying to get our attention.
The only difference of Vegas is they are a gambling capital, so I think it feels incorrect when you say "make the most of his experience" because that sounds like he will need to spend more money playing gambling there which is definitely not recommended.
Also, I'm curious if Vegas has adopted bitcoin at all..if anyone knows?
I read somewhere that few casinos in Vegas got bitcoin ATM. Obviously gambling must be one of the highly contributed industry on adaption of bitcoin hence Vegas casinos must be having some favour for bitcoiners for sure.
