How do I open a small business in a Las Vegas casino?

My American brother and his Costa Rican wife are coming to Las Vegas for her first ever visit to Vegas. My brother had a question, what happens if she wins a jackpot of some nature? As a foreign visitor if she taxed?  Will the casino withhold some or all the taxes? I'm sure foreign visitors have won jackpots every now and then, so what is done about taxation?

If I wanted to have a bankroll of $3,000-$5,000 for gambling, but didn't want to travel with the cash, what is the least costly option to get money? Will the casino cages cash a large check? Wiring ahead could cost $20 or more. ATM withdrawals usually have daily limits. And I'm visiting in April and I hate carrying a lot of cash. Can I deposit a few thousand with a casino host where I'm staying and gamble off that and withdraw some money when I need it? Also can I just transfer from my bank to the casino and use them like a bank? I'm a new visitor and wondering how something like this works or am I stuck using the ATMs and their exorbitant fees.

I have seen results from a $25,000 buy-in tournament on the strip which runs every couple of weeks with 18 to 36 entered. Since the IRS makes sure I have a W2-G for every payout of $1,200+ are the poker rooms bound by reporting requirements on these and other large cash games?

OK, so the governor signed into law upping the room tax at local hotels, supposedly to help pay for a new stadium to house the "Las Vegas" Raiders. I realize that increase won't cost visitors much more dough, but my question has to do with the timing of the imposition of that increase. When does it go into effect? Does the NFL have to approve the move of the franchise from Oakland to LV, or will visitors pay the increase regardless of that approval? I'm very skeptical that the NFL will approve the move, and I suspect that the extra money will simply end up being used for something else.

How is business at the Westgate and SLS? Whenever I am at either location, I never see much activity.

What is the difference between the Nevada Gaming Control Board and the Nevada Gaming Commission?

Any truth to the rumor that the Boyd downtown casinos will start charging a resort fee after the first of the year?

What is your take/interest in the Raiders relocating to Las Vegas? My take is I go to Vegas to eat-drink-gamble and have no time for live sports. Granted, I live in the Bay Area and can watch them anytime, and I really don’t wish to pay any higher hotel tax to cover the stadium cost.
