Looking for Input on the Grand Canyon Train.

I like trains and the history about trains. When we took the train we booked the Luxury Dome Class. It was a little more spendy but worth it to me. Children under 15 are not allowed on the car. We had a train ride with the Durango-Silverton ruined by three children that yelled,cried and basically a total nuisance during the trip.
If you do drive to the canyon there is an air Museum Planes of Fame on the way that is worth the stop if you like airplanes.
