We used Alamo for our rental car this trip and I am happy to report it went very well. I didn't use a coupon this time as I got a cheap rate for an Equinox for 8days May 13 to 20th. I did online checkin prior to us leaving. We arrived at MCO earlier than I had thought. We had asked to start rental at 11am, but our flight actually arrived early, we got our luggage and were bypassing that Alamo line in the airport by 10am. We took our luggage and proceeded to the car lot. No Equinox available so I took a Saturn Vue. Then loaded up the luggage and took my rental agreement I printed prior to leaving and headed to the exit. The rental agent takes your agreement and checks credit card and license and then you are on your way. It took a total of less than 10 mins!! The car was nice, new and clean. No problems at all!!
