Banjo - sorry, WDWFanUK instant messaged me about this post but, I hardly ever check my IM's!
The rental was with Alamo. We received a two door Toyota Celica which was lovely but, cramped and some of our luggage (two large suitcases and handluggage) had to go in the back in between the kids. Other than to and from the airport it was fine though. Our kids were three and six at the time.
