After looking over the postings I see there are a lot of Corporate Rate codes that when applied online, really cut down the cost! I've never used any of these before and I'm afraid that upon pick up or payment, they are going to ask for a corporate ID or some kind of proof for the discount. Have any of you had problems with this?? I see someone posted a corporate ID that would save me a lot on the underage surcharge fee (I'm 24), my only worries are that they'll question me about it...

Does Dollar require ID?
