We made ressies for a SUV through Dollar about 2 months ago because I came across a great deal - $199.00 for the week. I really would prefer a mini-van but the price was much more. Would Dollar consider a request for a change from a SUV to a mini-van an "upgrade" and charge more or a "downgrade" and call it even? That is if there are mini-vans available. Thanks to anyone who can help.
