The Limo company and drivers derive their income from a 30% portion of the party proceeds. If you don’t party for some reason, the Limo driver would expect a tip but you most certainly would not be stranded.
If you plan to book a hotel room it would be better to reserve a Sheri’s Hotel room rather than Las Vegas, because you will have more time to become acquainted with Sheri’s Courtesans and party. The Limo driver will pick you up from McCarran Airport and provide return transportation too.
