I rented a mid-size car for a week from
Enterprise, arrived at MCO on 4/10 around 4:30 pm. The line for the desk was a little long at 5 pm after we got our bags, but Enterprise also has kiosks to do the check-in yourself if you have a reservation. The wait for the kiosks was like 30 seconds, so we did that and were on our way to the garage within 5 minutes. I was almost immediately greeted by an employee in the garage and they brought me over to the mid-size row to let me choose my car. There were at least 10 cars in that row to choose from, so we loaded up and headed out. They did indeed honor my Costco reservation rate. It was easy, I would recommend Enterprise for sure.
