Haha, can't really complain about this place. Energy levels are super high and everybody is amped up when you land and are ready to party in Vegas...the exact opposite occurs for your departing flight back home.
Food wise, it's mostly chain restaurants and it's not THAT overpriced compared to other airports I been to.
Just some random tips..
-About $20-$30 cab ride FROM THE AIRPORT TO STRIP...about $20 FROM THE STRIP TO THE AIRPORT
-If you have a car rental, there is a shuttle that takes you to an off-site station. So give yourself some extra time!
-Lots of walking...yep, LONG walks trying to get to the different terminals and gates.
-You will probably get lost from the baggage claim area. They have separate exits for cabs, limos, shuttles, pickup.
