Here's what coronavirus has and hasn't changed about Sin City

My comments.

As long as US keep getting this very high infection rate, nobody residing outside US will want to jump in Vegas or in US. (An exception are those degenerate poker players not knowing what are the real effects of a covid-19 infection)
USA is still the most Covid-19 infected country along with Brasil, India and Mexico (right now).
Not mentioning that aircrafts, especially long haul flights, are among the best places to be infected.

Checking the temperature is a total bighornsh.it. Anybody, infected or not, before entering a premise or an airport would like to be heavily loaded by Tylenol or ibuprofen or aspirin assumption.
Moreover many Covid-19 infection cases went without any fever and, sigh, without getting a positive test.

Buffets, imo, could be reopened as long as single portions of food would be available and where no customer can touch other than a single personal spoon.
And of course where a proper social distancing comes in order.

Parking fees: it's a total another bighornshit to make people pay the parking when entering a casino.
Did we need to get covid-19 to accomplish this?

Smoking.

It's a third rattlesnakeshit to allow people to smoke inside a casino, unless a very strong air ventilation is used. A wasted opportunity to stop the fkng smoking into a casino.

Imo and in the opinion of many, Vegas casinos will make a safe environment if:

- every person entering the premise must wear a face mask (not allowed a FFP2/FFP3 mask with a valve)

- many gel sanitizers are at disposal, forcing people to clean hands before any table/slot join or before/after any toilet enter/exit and buffet/restaurant enter/exit.
Covid-19 is very susceptible to any alcoholic/bleach solution.   

- a proper air ventilation is in order (many high end casinos offer a kind of clean air long since)

- no smoking is allowed. Smoke endorses the probability to get virus particles trapped in the air, thus increasing the probability to catch the unwanted fkng covid by simple breathing despite of the use of surgical masks.

- any person will constantly keep a "social distance" of at least 4-5 feet from another one.

Unfortunately long haul flights cannot guarantee a safe environment by any means.
An aircraft is the prototype of an indoor same breathing air enviroment, even if seats are distanced.
Probably only FFP2/FFP3 face masks and gloves wearing and a deep disinfection after any flight is the solution to lower the risk. It's like entering a covid-19 ICU, no more no less.

I think the Park MGM in Vegas ( formerly the Monte Carlo hotel in Vegas )  just became a             non smoking hotel ..which may be a smart move since probably about 80% of the vegas visitors do not smoke and if they can capture a significant number of customers then maybe a few other vegas casinos may follow ..just like a few casinos dropped the parking fees due to virus ...but I think as soon as business picks up the parking fees may come back.

By the way, casinos don't care one bit if an employee or customer gets lung cancer from inhaling about 2 packs a day of  second hand smoke.....its all about the money

Yes, it would be a good start if MGM made smoking free one of their premises, imo.

I highly doubt Vegas will go totally smoke-free, might have a couple here and there that do it at their own property.

Some more in the midwest has implemented no smoking now, we have a state or two that's been totally no smoking except on tribal lands prior to C19, which tribal can do whatever they want but they have posted that they are no smoking in 90% of their casino floor space since they've reopened. As long as there's no casino next door smokers won't go anywhere else, it's been proven at other casinos and other properties. They'll just go outside, they'll get their smoke on and then they'll come back in and then continue playing.
