Just popping in to say i have a Kia Carnival also and i love it. I can get my double jogger in to the back with the seats up and also put things around it. I like the fact also that Kimberley and an adult can get through the gap as i sat in the back when my dad and step mum was here. When this bubs is born i am thinking of putting Kimberley and Alex into the back and having one of the other seats down so i can get to them easy.
