This had to be planned well in advance. As one local pointed out on Fox, those rooms for the festival dates were sold out months in advance.
“planned well in advance”
I happen to agree with the advance planning, but as a “what if”...
With the Squeeze Marylou reported to have worked at Mandalay Bay, could she have been able to grab a canceled reservation or an early check-out in a prime sniper location?
Or maybe just got Room Service key to someone they knew wouldn’t be there (event crew)?
Maybe those with hospitality experience could weigh in on this. Of course, maybe this detail will be out publically soon enough.
