Find a Skycap. Let them know they can help you with your luggage. Give the guy a nice tip and tell him you want to go to Yellow #1. Here cab drivers will get pulled out of the long cab line servicing the regular folks in order to pick you up at Yellow #1. No waiting.
Now during super crowded times even this Yellow #1 tip can have a line behind it. What do you do then, or for that matter if you want to take no chances on waiting in line? When your plane lands and the pilot allows you to turn on your cell phone, Twitter Vegas Cabbie (he is the one who gave us the above tip in the first place) and tell him your flight just landed and you will gather your luggage and meet him at Yellow #1.
He, or someone will @ reply you and by the time you get your luggage and head out to Yellow #1 your chariot will await you.
Ah the joys of social webbing in Vegas.
