I have been looking at prices to rent a car to go see the Grand Canyon while I am in Las Vegas. The best deal by far seems to be with Thrifty - $150 for 3 days with a convertible or $80 economy car. However, is the airport the only place to pick up the car? Ideally would like to pick up from Flamingo and drop off at Planet Hollywood.
It probably will still work out a lot cheaper getting a taxi to and from the airport to pick up/drop the car.
