Can I pay with cash

I never heard you can pay cash? But I do know you need credit or debit card. From past experience just have a credit card on hand. Hertz, can be wishy-washy on how you are going to pay. If your credit good or bad they still mighy ask for credit card. FYI, if your credit is not good they might not accept your cash.

No

You need a credit card to reserve a car. You can pay with debit if you have a return ticket according to the policy on their site. Never tried cash but the fact that them allowing debit is so new makes me think no.

Yes

Yes, but you still might need a credit/debit card for deposit. It depends on your credit
