Can anyone tell me what models might be available in the standard aisle for Hertz at MCO? Are you assigned a vehicle, and if so, are you able to switch if unhappy with the model assigned?
Hertz will assign a vehicle to you, you don't get to choose from the aisle (like with Alamo or National).
Sometimes they will give you a choice if you ask at the counter.
We had a full size booked and when we arrived at the counter, I asked what they had for me.
They gave me a choice of a Buick LaCrosse or a Chev Equinox (a Premium and an SUV, no actual full size offered)
Your mileage may vary as to what they have for you in Standard size, but I would definitely ask up front what is available.
