Obtain a list of car rental agencies in the Orlando area. Orlando is home to at least 24 different car rental agencies as of October 2010 with some of those having multiple locations all over the city. A list of car rental agencies in Orlando can be obtained at the Orlando International Airport website or from the Orlando Yellow Pages website, both listed in this article's Resources section.
Contact car rental agencies and ask for rates. This can be done either over the Internet or via telephone. When you ask for rates, remember this advice from Frommer's Guide to Getting Around in Orlando: "The further out you can book a car, the less expensive your rental is likely to be." This is where flexibility can be an asset in getting a cheaper Orlando car rental: If you are willing to schedule your rental several weeks or even months in advance, you can beat the tourist crowds and possibly secure cheaper rates.
Ask all car rental agencies that you contact about special deals for tourists. While you may not find many special deals during the busiest Orlando tourism months (June through the end of September), the period from October 1 to May 1 is typically the slowest time of the year for Orlando tourism, according to Mouse Planet. Some car rental agents may be willing to offer extra discounts for Orlando visitors, especially those who visit during the slow months.
Make your car rental reservation only when you are certain that you will not need to make any changes to the reservation. Since Orlando car rental rates can vary widely in even a one-week time span, you need to secure your rates early and leave the reservation intact to get the cheapest rates.
