What annoys me is that (the last time I was there) LAS was listed as part of the MGM stop, so one night I decided to see if that was true. After hopping a couple of fences I wasn't supposed to, I gave up after about a mile and cabbed it the rest of the way.
Personally, unless I'm going more than 3 stops, the Monorail is utterly worthless.
I think the best quick-fix would be to run The Deuce straight to LAS after stopping at NYNY. Right now, it goes all the way to the SSTC(?) then you have to transfer to another bus, bascially taking the long way around the airport.
Stupid taxi lobby.
