Definitely need a credit card

You'll need a credit card. I paid thru rentcars.com but Alamo charge 1 dollar in my credit card. The tolls and possible fines will be charge in credit card

You should verify with your bank. Most of insurance coverage is provide when you use credit card.

Better check with them. Every company is different wnd kigjt require a deposit in your debit csrd
