Simple to use. Book online. Turn up and drop off car. Get taken to airport with minimum delay, approx 2 minutes. Arrive back, phone company - never had to wait more than 10 minutes from making the call. Whats not to like.
OK, so they want me to review my online booking 'experience'. I was online I booked I paid If there had been a moment that fell below 5 stars during the booking process I would have stopped and gone somewhere else so it was OK, pretty average but how do you make a booking 'experience' special anyway?
