>"A spectacularly helpful reply JLS."
Just sayin' perhaps the OP might be being a tad optimistic to expect to be able to hire a specific make and model and it would perhaps be prudent to plan for the eventuality that, when he gets to the desk, they offer a different car, ie be ready to cough up for an expensive up-grade to get the required luggage capacity. Of course if you can give the OP a guarantee he'll get a Renault Kangoo then that is obviously much more helpful than my post. :¬)
