Mini-Vans are considered a premium vehicle, have limited availability, and generally have special conditions. Most car rental companies, now, require a credit card guarantee (or deposit) and will charge a penalty if the reservation is not cancelled within the penalty period. Because of the increased conditions of rental, reservations easily error-out. If you have made more than one attempt to reserve a Mini-Van without success, please call the Travel Service Center at 1-800-874-7317
