Kayak.com sucks when it comes to doing their job. Do not book a car with them or with Dollar/Thrifty. I wish i could give a zero and not a 1 for ratings. Poor customer service on both ends. Gave me this around Kayak that Dollar owed me the refund then Dollar same thing on no Kayak owe you the refund. I would suggest dealing with the actual car rental company like Enterprise etc but don't book with a third party. From personal experiences. Second time trying Dollar car rental. Never again... You have been warned..
