Upon arrival in Las Vegas, I decided to take this shuttle as opposed to other modes of transportation like a taxi. The Airline Shuttle Corp had the biggest presence with a kiosk and a sales person. She recommended a round trip ticket, which was about $13 per round trip, the savings was about $2.50 vs buying one-way fare.
There is a wait to ensure there are at least 5-7 people per departure from the airport onto the strip. They give you a sightseeing booklet that doubles as a ticket, which the driver scans. I bought a round ticket so I ripped the ticket page out and put it in my wallet for safe keeping.
The shuttle was air conditioned with tinted windows. The complete drive to the strip took less than 10-15 minutes. Each shuttle stops off at its scheduled hotel.
If you are in a rush I would recommend a faster service, however, if you have time to spare take this shuttle service.
