As far as your Tram idea goes the monorail, http://www.lvmonorail.com, has talked about expanding to the airport for a while now. But the Monorail has seen one problem after another, from going way over budget when it was built, to operating at a significant loss since day one. The locals oppose this expansion for good reason. It can not even break even after all these years! It only services the east side of “The Strip” is one major problem in my opinion. What WERE they thinking?? How many people want to have to get off, and lug their luggage several normal sized city blocks when its 100 – 115 F in the summer to get to their hotel if the closest stop is not at their hotel? Not very many, think about it. Which is why most business travelers prefer cabs when jumping around the strip so they don’t show up in a suit and tie looking like they just stepped out of the sauna. Now if your staying at the MGM and your going to the LVCC for some convention then its great, no major walking involved. But more times than not the Monorail is more trouble than its worth. Bad planning strikes again.

I think your mobile Share A Cab idea is great. Although it would hurt cabbies a bit. Then again it would ease up traffic some on the strip which is much needed for all.
