Don't use Snowmad Transportation. I made reservations on 12/30/07 for pickup and return trips from Salt Lake City to Park City for 2/23/08 and 03/01/08. Both trips were charged to my credit card ($238) a week in advance of arrival for more than advertized on their website ($89 each way - still shown as of today on their website). When I called to question the billing they were verbally abusive about even questioning their rates - and said they would just cancel my reservation because they didn't want to do business with me. As of today they have only refunded for one trip ($118). My complaint to the local Better Business Bureau went unanswered as well.
If the Better Business Bureau didn't want to help the customer there must have been a legitimate reason. We canceled because of abuse that our drivers would incur. It's tough when people come off a long flight and they are disgruntled from the start of a vacation. We do the best to make their trip as comfortable and inconvenient as possible.
