flew into and out of McCarran last week. no hassles or problems whatsoever.
shuttle service to our hotel was handled quickly (TI doesn't have its own, but there are small buses that will do it for a small fee).
well, aside a slight security issue when a corkscrew/bottle-opener/knife inexplicably turned up in my friend's luggage, but that's a story for another time. we're still trying to piece together the previous night...
