You can't use it as a one way rental though, since PL doesn't allow that. I've used PL for cars. I think it is a lot harder to get a great deal on a car than a great deal on a hotel though. The price difference for hotels can be a hundred dollars or more. With cars, in my experience, the difference is very small. The situation is probably different in different cities though. Orlando is probably a good place to get a good deal.
