There are cabanas on the property that could have vent windows but typically in the newer constructions they don’t want windows opening in the towers for reasons learned from the old MGM fire. Opening the windows allowed the fire to spread faster and further than it would have if the guests were not opening the windows. The newer buildings also have firebreak/containment doors that are normally held open but in the event of a fire alarm, are released allowing the closures to close of certain sections.
Also, given that it is a casino, they probably want to avoid jumpers who are facing huge losses.
There is a casino near where I live; the number of suicides is unbelievable. People end up owing a lot of money to some very bad people.
There was one man who was addicted to poker; a friend who worked there told me that one night, his pinkie was cut off. The next night, another finger was cut off. And she never saw him again.
