How much space in a Ford Galaxy / VW Sharan?

[CCCS]

I need to hire a vehicle to take 6 people (3 adults) plus 4 suitcases. Would all this fit in a Galaxy or Sharan (cough)?

Last year I hired a Ford Transit which was bigger/more basic than I needed.

It's a hire firm in Portugal and like most hire firms it will be a gamble as to what they actually have and age.

It seems too borderline, I think I'll go for the Transit again.

Thanks chaps.
