I'm a former native New Yorker (born in Brooklyn) and even I can't see any purpose for a monorail on the Vegas strip.
When my wife and I were there we'd walk the entire length of the strip up and down 5 times in a day. What's a monorail for?
It seems that a monorail would be counter productive in that you'd miss a lot of hot-spots being that so many of the kool places are bunched up together.
An FYI as an aside; coming from an area where public transportation is ubiquitous only causes one to despise it, not desire it.
In the summer?
Personally, I won’t go the Vegas in the summer.
Kinda like going to Palm Beach in August.
Why?
Maybe the did the monorail all wrong. Being Vegas, perhaps they should have theme-parked the monorail; like how about the “Taking of Pelham 123” monorail? That might be worth riding.
