Recent Minvan rental with integrated car seats?

[momofbgtwins]

We will be traveling to Orlando 9/06. (Me, DH and twin DS and DD 4 yrs old) I haven't booked a car yet. We used to go with Avis because we almost always got a minivan with integrated car seats. When we went this past March Avis had NO minivans with integrated car seats and said they were no longer buying that option on their minivans. (We had included 2 safety seats on our reservation as we know no rental car company will guarantee integrated seats)

My question is - has anyone recently (within a month or so) rented a minivan at MCO and had integrated car seats, and which rental company was it? (I am only interested in the companies where the rental desk is in the terminal- Dollar, Budget, Alamo, Avis, National)

Thanks in advance!
