I wish I could say this is a good airport but can't. The overall design is poor. Exit plane at terminal 3 long walk to tram (train) to the baggage area and ground transportation except it's another long walk to the exit for the transportation. Just to pile it on, then it's a long walk to the taxi stand.
Look, I run and hike for miles every day but would rather not when on vacation at the airport :).
Of course the designers of Mccarran did manage to put in several hundred slots when you get off the plane. Would have been nice to have the tram there.
