I booked my car through Kayak who took me to the Priceline site to book at car at Dollar Rental Cars at the Burbank Airport. When I got to the Airport, with my happy notice from Priceline congratulating me about my rental, the Dollar people could not find my reservation in their system. I showed them the confirmation but it made no difference. They, along with the other car rental agencies had NO cars to rent. We were essentially stuck. Thank you for nothing Kayak and Priceline. It appears whatever you were to communicate to Dollar never got there. Very disappointed. My advice to people looking to rent a car is, you can use Kayak to check prices but to book directly with the Rental Agencies. You just can’t trust these intermediaries.
