Incompetence sums it up. Book 15 passenger van for teens Birthday party at arcade. Get reminder day before rental(so they knew). Arrive to "we do not have a 15 passenger van will you take two minivans for same price instead?" Since I can only drive one vehicle at a time I turned down the offer. No other solution provided. Nearly ruined the party but other parents stepped up to help drive the group to the destination and back. As I said, incompetence and loss of a customer for life. Rental customer beware.
