Alamo uses the terms Midsize, Standard, and Fullsize. At MCO, there is an Midsize aisle and a Fullsize aisle, but no Standard aisle. If you rent a Midsize, you select your car from the Midsize aisle (usually described as a Hyundia Elantra or equal). If you rent a Standard car, you are directed to select from the Fullsize aisle, as is the case if you rent Fullsize (usually described as a Toyota Camry or equal). I've read that sometimes there might not be any cars on the Midsize aisle so you get directed to the Fullsize aisle, but I've not had that experience myself. I usually reserve a Standard car to take advantage of the lower cost compared to reserving Fullsize. I book through Costco and then go to the Alamo web site to link the reservation to my Alamo Insiders account so I can take advantage of Alamos's "skip the counter" service and go directly to the garage/aisle to select my rental car.
