I will be in Vegas for 3 nights in February for my birthday. We always get a limo to the hotel and typically just cab it or walk if we need to get somewhere(typically the strip or downtown). This trip I am wanting to take a day to go exploring off the strip. What would be the easiest/least time consuming way to rent a car for a day? Do I need to take a cab to the airport/car rental lot get the car and then take a cab back to the hotel the next day when I return the car? Are there shuttles? Do any of the car rentals deliver?
