Always connected to the Las Vegas Strip
Various hotels offer some cheap and often free shuttle services to and from the airport.
Away from Las Vegas Boulevard, hotels, such as the M-Resort, also provide free shuttles to the Las Vegas Strip, to Downtown and back.
You can find the information on the hotel website or ask the Concierge for the shuttle services offered after your arrival at the hotel.
For high-priced room categories, or as a High roller, guests usually have a free limousine, which goes exclusively to the desired location.
