Ride share on The Strip is very convenient and affordable considering the time and now the cost of valet parking.
However, venturing beyond to other points of interest becomes costly. I like the convenience of renting a car from the Hertz desk inside The Cosmopolitan.
I rent a car for the day and gang my itinerary accordingly. Treks to Chinatown, Downtown Vegas, and Summerlin would be an expensive ride share.
20% off if you're a guest at The Cosmopolitan. The cars are available in the Self-Park Lot and with my Cosmopolitan Identity Rewards level, parking is free. It's also easier and faster than renting at the airport.
