AWFUL. We were planning a trip to Napa and booked our hotel through Kayak.com. HOWEVER, when we arrived, it turned out that the hotel had been mapped incorrectly in their system. It turns out that the hotel was over an hour away! At first, Kayak.com did not even acknowledge their own error. After we got them to acknowledge their error (in writing) they stopped returning our emails about getting a refund. Thankfully we used AmericanExpress and they promptly refunded our money (wagging their finger at Kayak.com all the way). An awful customer support experience. I would expect more from a company founded by a Kellogg grad. What a joke.
