Alamo were very good and we just took the car to their location by Magic Kingdom (although we could have opted to let them come and collect it) where they quickly exchanged it for another car.
DH is rather pleased with the black 2-door Dodge Challenger they have given us. I think Jeremy Clarkson would describe it as a 'muscle car'.
We decided to go to SeaWorld after we got the new car and went in the new Antarctica attraction, but both DH and I were not that impressed. Sorry, SeaWorld, but we preferred the old penguin encounter.
