Be sure that  you bring your valid drivers license. Make certain that it won’t expire during your trip.

Check any credit cards that you might be using.  Be sure that they won’t expire during the trip and that the limit is high enough to cover all expenses and possible emergencies. If you need the maximum raised, ask the credit card company well in advance.  It normally takes time for a higher limit to go into effect.

Verify your coverages with any insurance companies and credit card companies.

Call the company to update your reservation. Inform them of the new time of arrival so that they will have a car available for you. Ask them to honor the original rate on your reservation. Rebooking could raise the rate.

Always get the name of the person that helped you and make note of the time of your call.
