Used Avis to rent a van from MCO to PC back in April 2007. Avis had us wait about an hour after checking in w/ them. They said that they still needed to prepare the vehicle for us. We were a bit bummed about waiting since we were tired from flying all day from the West Coast. They gave us a Chevy Uplander with a DVD player which was a nice perk. The only downside was that the automatic right sliding door didn't work after a couple of times of use. It wouldn't close. After manually forcing the door to close, we had the kids climb out the back the rest of the time.
We drove up to the PC rental office the morning of embarkation to return our rental. The office is not far from our hotel or the terminal. We didn't have to wait very long for the shuttle van to take us to the terminal. Our family of four and couple heading for a Carnival ship were the only passengers on the shuttle. The ride was pleasant and the driver was helpful. We'd use Avis again with the hopes that next time, we won't have to wait too long for our rental and that they'd give us a van w/ doors that work, LOL!
