@Cigarguy A good friend of mine has an autistic son. He likes routine and familiar so they got a motorhome so he would have his space that was familiar. Just a thought. I don't know if this would work for you and your family or not.
@Musicman I think it would be something to look into if we're going to travel more. Because hotels and planes wouldn't be a great idea for me. And it would be easier for all the kids to travel this way.
