Okay this is a 10 second clip of very cherry picker shots. The first one outside faces treasure Island, the sun is hitting it pretty hard, so I would say it's fairly early morning. Anyone who has ever been to Vegas will tell you that surprisingly, the floors are pretty empty in the morning. You know, because everyone is asleep.
This also could be a random Wednesday at 9am for all I know. Not exactly a reliable source here.
Not saying it's not down in numbers, but if you cherry pick your shots it will fit your narrative pretty easy
