Re: Traveling with children...

I think the majority of our trips has been with a kid but never more than one at a time; one 11 and one 12-months. We used the rear-facing bucket seat (just behind the co-pilot's seat) in our U225 with new seat belts and that's where they sit. Not easy to keep an 11-year-old in one seat. though.
My plans include securing the recliner (which now just sits on the floor just as if it were a stix-n-brix house). I am going to drill through the floor and send a 1/4" rod up with a hook on one end and thread the other end so that I can use a fender washer to spread the load underneath and a nylock nut underneath. The idea is to hook the base of the recliner and hold it in one position. Then another seat belt instllation. We have only one seat belt on the sofa right now but plan on installing another. This will give us 5 passengers plus driver.
Our coach also has that little half-dinette which I did not much like at first but is perfect for setting up a kid for meals. It's a bit tight for us (ahem!) bigger folks, however; but I can still manage to wedge myself in. Not an easy seat-belt install there, though.
You seem to be planning on carrying quite a group.
