I bought a ticket from DIA to downtown Denver instead of using a taxi. About 15 minutes after the scheduled arrival time they said it would be about another 10 minutes for the shuttle to arrive. 20 minutes later I went to the counter and asked to cancel and for a refund because I was going to take a taxi. He said that he logged out of the computer and could not refund my fare. But, I could come back the next day for a refund. That's a 60 mile round trip for me for twenty bucks. I don't think so. Stay away from these guys, put your twenty bucks toasted the cab ride instead.
