Making A Reservation
In some places you may be able to walk in and rent a car without a reservation. But to make sure you will have the type of car you want, when you want it, you should reserve it in advance. Most rent-a-car companies take reservations in advance and will guarantee them with your credit card number and arrival time. Often they will provide a reservation number which you should record.
When you call for a reservation, give the time and date you want the car and your preference of model and make. Major companies will reserve a car in the cities they serve in the U.S. and even in foreign countries.
Many established rent-a-car businesses have toll-free numbers which can be called from anywhere in the United States without charge, 24-hours-a-day.
Do: Make a reservation when possible. Recheck your reservation as close to the rental date as possible.
Don’t: Forget to cancel if your plans change; this releases the car for someone else.
