We were misdirected to take airport shuttle and ended up 30 miles from our car rental agency. It wasn't fun to find out that we couldn't cancel since the entire amount was going to be charged--whether we actually rented the car or not, and no way to transfer the booking! Fortunately, the people at Enterprise were super helpful and we were able to get into town to get a car. No help from economybooking, but thank you Enterprise.
