Are the skycaps able to bypass the "brownshirts"?
You can email hackingvegas at gmail dot com and he will do a private pick up for you if he is working, you can also follow him on twitter to read some interesting cabbie stories.
If its just you and you do not want to do a limo nor wait in a cab line, just do the Belltrans VIP service. It is $28 round trip, you book through their website and you will get a Towncar, SUV or Limo, you MAY have to share with another person but as they call it a ride share, I never have nor have anyone I know, they always got it by themselves.
