Time is essence in most cases and specially when you are tired already from flying and have to drive to the hotel after that. If the service is fast, effecient and hassle free, there is nothing more to ask for.

Like: The car, a Ford Fusion Hybrid, was an excellent, well-designed and maintained piece of equipment. Great car. Rate did not match the reservation rate (it was higher, due to "taxes and fees", but was quickly corrected, once I showed the printout and e-mail, which did include taxes and fees.
Dislike: That the rate was higher than was what was contracted for. Fortunately, I had printouts and e-mails to prove it.
