Before renting a car with Worldwide Reservations, please make sure you have your driver’s license and a valid credit\debit card in your name with you. Worldwide Reservations – as most car rental companies do – will require you to present a valid credit card as a guarantee, in order to cover for incidental charges such as parking tickets, traffic violations, missing fuel. Debit cards are generally only accepted as a form of guarantee with a few companies, check their terms and conditions. Cash payments are normally now never accepted.
