Not a good airport for travelers.
It takes ages to get to and from your gate, with the most ridiculously unneccessary monorail in history. Security lines are very long, TSA is awfully slow here, and with all the smokers outside and all the slot machines inside, this is not a great place to land or depart from, and for an airport so close to Vegas, still takes a $25 cab ride to the Mandalay Bay?
Speaking of cabs - expect to wait in line for one. And I mean a long line. Rental car? Dont even think about it. Between the buses back and forth - and the location weird - that ends up being an utter goat rodeo too.
