Angel, I think the centre row is best. There are anchors for the tethers behind the centre row, and you can get to the children easily. I'm not sure if you can tether a car seat in the back row....& it's a pain for getting kids in & out.

Shower, ah yes, we went through this just yesterday when everyone had showers & I shivered through mine. Usually it's not a problem because I rarely try to shower in the morning unless i'm up very early. I have mine after the biggies go to school, or at night.

I grew up in a large family & it's always a bit of an issue. Best not to be too regimented about it, I think. It's a real problem only when everyone has something to be ready for at more or less the same time. When you think about it, that doesn't happen too often.

ROFL, for my wedding day my one request (I was at my parents' house) was that I got the first shower of the day!
