Find a shuttle that goes to rental car area . Let them know which rental place you are going. It’s different ones for off airport rental places as well
There are car rental places in the baggage pick up area or signs to them
Look up online McCarren international Airport car rentals online and it should pull up some car rentals at the airport or close by and if you need to ride onto the strip take the numbered busses because the busses with the names are more expensive because they are strip all access busses depending on where your staying its better to take the bus cause you'll save alot of money
Dollar Express is the best way to go
