KAYAK’s top tips for renting a car in O'Fallon

  • Car rentals in O'Fallon, Missouri make perfect sense. You can explore the town on your own schedule, visiting the galleries, parks, breweries, and spas by day, and enjoying the clubs, bars, and restaurants by night. In O'Fallon car rentals, you can take I-70 East into St. Louis or west across the state to Columbia or Kansas City.  You could even head northeast to Chicago or southeast to Nashville, or head north or south, following the Mississippi River.
  • The St. Louis Lambert International Airport is the ideal airport to fly into when you are visiting O’Fallon, Missouri.  Located just 30 minutes east of O'Fallon, the St. Louis Airport is not only an easy drive to O’Fallon, but also a convenient place to pick up the car rental you've reserved. Free shuttles from the St. Louis Airport Arrivals curb will take you to various rental car agencies located off airport grounds. Some agencies you can access from the St. Louis Airport include Avis, Hertz, Budget, Enterprise, Alamo, National, and Thrifty. Once you have picked up your rental vehicle, take the I-70 west to O'Fallon, Missouri. Do not get this city confused with O’Fallon, Illinois, a city located to the east of St. Louis Lambert International Airport.
  • O'Fallon, Missouri has won awards for being a wonderful small town to live in. As a typical small town, O’Fallon tends to follow small-town traffic patterns. Driving is more congested in the more central, downtown areas where the shops and restaurants are located, and drivers in O'Fallon car rentals should be careful when driving near parks and schools. When driving on residential streets, drivers need to stay alert for both children and animals running unexpectedly into the road. As you are driving through O'Fallon, you'll very likely drive along O'Fallon's Path of Heroes, a road approximately 8 miles long running through the heart of O'Fallon and passing several city landmarks. This road memorializes those who have fought and died for our country.
  • As O'Fallon, Missouri is on the outskirts of the St. Louis metropolitan area, this small city is subject to commuter traffic congestion. Traffic tends to be at its heaviest during rush hour, usually between 7 am and 9 am in the morning and 4 pm and 6 pm in the evening. Drivers in car rentals in O’Fallon should be especially wary of traffic congestion around the entrance and exit ramps to I-70 and I-64, two interstates that border O'Fallon on the north and south.

Staff was professional

Cons:

During the booking there was NO mention of the $200 security deposit. Because I was unprepared for this I was unable to even rent the car and missed my chance to both see my family and visit my grandfather's grave.
