Can not say I would use Kayak again.
Pros: You offered an excellent price and reservation process was simple.
Cons: When I arrived at the counter the confirmation I repeatedly gave as well as showed the agent came under someone else's name with a pick up in Florida (I was in New Hampshire). The agent was confused, contacted her supervisor, and then offered to give me the car under the other person's name which I felt was quite unacceptable. I had to cancel the reservation, cancel the insurance, and then rebook which of course was at a higher price. Very disappointing and time consuming.
