For sure, but especially on the Nozomi service (the only way to travel to avoid tourists blocking the aisles with a huge quantity of baggage) the green car is really exclusive and happily not included in the Rail Pass. A heaven of peace.
In the OP's case I think he should not worry to travel with the slower (but still fast) trains (with more stops) in the green cars where many people will have bags and less "managers" on board.
And just buy one of these delicious apple ice creams (very frozen) from the passing attendant for the children. It will make them happy.
BTW: Traveling light will always make you look better.......
