Cons:Roadside service charge wasn't included in my quote when I reserved from Kayak. Don't know if this screw-up was Kayak's fault or their, but I don't care. I didn't sign up for roadside service, it's included in my insurance and I denied theirs. I was told it was "legally required" in Puerto Rico. Nowhere else in the US is there a "mandatory road-side service" fee, that's completely ridiculous and an insult to my intelligence. It was just $5/day. Looks like others got scammed a lot harder with this company, so I guess I can't complain too much. Do your research, don't skimp, just go with a real car rental company and don't bother with Kayak if they can't even guarantee you the real price after all taxes and fees.
