Here's a tip: If you want some extra cash before you leave the airport, make sure you head to the Wheel of Fortune quarter machines in the Delta wing. I put in $1 and won $50 on my first try! On a different machine in the same section, I put in $2 and won $7. Of course, you have to see the casino attendant to turn your ticket into cold hard cash. But it was the highest I won of anything during this trip to Vegas.
Looks like I'll be spinning the slots before I head to the city next time. Lol.
On a side note, I was in the Delta departure gate, and no sign of any Mexican food anywhere, so I had to settle on Ruby's Diner (bleh). Also, there is a manicure place, if you want to kill time and have a long wait before your flight.
