The non smoking casino on wonder was supposed to be a high roller casino when it was destined for China, they repurposed it into a non smoking casino when it was redirected. So they clearly don’t think there is a market for a high roller casino outside of Asia.
there are a fair number of non smoking gamblers, but fewer than the smokers, so it makes sense the smaller room would be allocated to non smokers. There were lots of happy people when smoking was banned in the casino during covid, so maybe the feedback showed them there is a requirement for a non smoking casino? The current system of smoking and non smoking sides just doesn’t work.
I will be in wonder later this year and happy there will be a non smoking casino, just hope it has decent machines.
