Thanks to Graytleegray and rossx for your replies.
Subsequent to my posting I did some internet research:
I'll be in LV for three days. Thought that I'd take a one day trip
to Laughlin. I investigated car rentals and could rent a car at the
Mirage or Bellagio for $35/day incl. taxes. However I can rent a car
at McCarran for three days( Dollar Rent A Car) for a total of $58
incl. taxes. I made a reservation for this. I've never rented a car
at McCarran. Anyone have any opinions/thoughts /advice re: rental, in
particular Dollar Car Rental. BTW Dollar was significantly cheaper
than the other major companies.
