Can't say \"it's the worst\" airport shuttle service in Las Vegas simply because I haven't tried all of them. However, there's nothing good about this one. Best advice would be to avoid this company even if it's FREE!! This is if you would rather avoid a y hassles. It took over an hour and a half to get from the airport to my hotel (Vdara). On the return, I\nWas scheduled for 9:25Am pickup. By 9:35Am, called to inquire how much longer before the shuttle arrive to pick me up? They indicated they already came by and left at 9:25! They are very BIG LIARS!!!! I've been out in front of my hotel since 9:17 with no sign of the Showtime shuttle van in sight!! I should've did some research prior to paying for a round trip ticket!!! End up spending $14 plus tip for a relaxing carefree cab instead. Should've went with the cab option in the first place!
