Going to a local place doesn't necessarily mean going in shitty places, even with family. I traveled in many countries, especially Europe and Asia, with my 2 daughters and while they do throw the usual tantrum for their ages, we always find something local they like to eat, and they don't really mind one room or another to sleep, as long as they are in the same room with at least one of us.

>and worrying for days afterwards about the effects of smoke, mold, dust etc on their health.

I mean, that one is on you. It is possible to go on vacation even camping with kids without having anxiety attack over everything.

Also, while some kids are difficult and kids are slow and certainly limit you, hours of tantrumps every holiday and impossibility to eat are not normal.
