Does anyone have a Kia Grand Carnival? What do you think of it?

We're looking at getting a bigger car because at the moment if the whole family want to go somewhere together we have to take both cars as we are a seat short.

My main question is about the seating. I'd prefer not to put the littlies in the very back row, so if I were to put a baby seat (one forward and one rear facing) in the side seats of the middle row, can people get into the back row without having to remove the baby seats? I'm thinking it may be possible to move the entire seat that has the forward facing baby seat forward enough to give access to the back row of seats, but I haven't had a chance to go look for myself to see if this is possible.

Does anyone have a Kia Carnival with more than 1 baby seat in it, and if so, where do you put the seats?
