Booked through Hot Wire. Car was clean and and readily available. Simply walked to the proper section and took any car I wanted. Good price for a Hertz Rental and the location was at the LAS Airport .
Only drawback was that you don't deal with a person at the counter. I used a Video Kiosk. The agent was helpful and courteous but the sound was poor and I don't like using a phone set that probably never gets cleaned.
