Yes, with the Prestige Collection vehicle, it's pretty much guaranteed something from that class so it may or may not accommodate 6 people.

Regarding booking through the Hertz app, it depends. Hertz is playing around with cancellation penalties lately. I would avoid putting in your credit card wherever possible. In the vast majority of cases, making a reservation does not require a credit card, so obviously if they don't have your card on file, you can cancel anytime you want. If you did enter your card when booking, just call Hertz to inquire.

Regardless of where/how you booked, use the link below to track the price of your rentals. It's likely we'll find you a better deal eventually.
