I've asked a couple times but never had a need for a rental yet. They said they would help return the car. But I'd love to hear some first hand experiences.
I'm also curious on the picking up a rental car. I figured if they wouldn't help, I'd probably leave the family to hang out in the suite while I go pick it up and then just drive back over in the rental to PS. The picking up is probably harder because Hertz or National isn't going to just hand your car over to someone else probably.
