I have made multiple reservations trying to get the best price. I have 2 with Hertz, 1 with Alamo and 1 with Thrifty. I have read on this forum that people will make multiple reservations and just go with the car rental that has the shortest line. Do you have to cancel the other reservations? The reason why I have 2 with Hertz is one shows an extra driver no additional charge and the newest cheaper one doesn't. Does it make a difference that I have two or can I use which ever one has the best rate at the counter?
If anyone can shed light on how rental car agencies work I am interested in finding out more. For example, how do they determine how many cars they keep in stock? The last time I rented a vehicle, I requested an economy, they had run out of vehicles and I ended up with a brand new SUV with in-transit stickers. Granted this wasn't in Vegas but in Grand Junction, CO during the Jr College World Series. I would be interested to know if they have deals with car dealerships when they run out of cars and then they just borrow off the lot.
