OMG, that is so weird, I was just complaining about my Thanksgiving to some other friends -- I have almost the same problem -- not smokers, but asthmatic children. My friend's son is severely asthmatic, yet my SIL was planning on coming over here with her child who has bronchitis, never even bothering to consider my friend's son - who's immune system is compromised and he can NOT be around sick children. SIL is so selfish she will come anywhere that she doesn't have to cook, and she doesn't watch her kids either, so her daughter is sure to be coughing on everyone. I told her she was to get some antibiotics for the child, and if there is any thought that she might be contagious on Thanksgiving, she was to not come.
I'm a former smoker (yay for me!), but I never smoked in my home. I never wanted guests to be offended, plus it stinks up the house so bad anyway, there is no getting that stale smoke out of the curtains, off the walls, etc. I cannot see why people just can't step outside for a smoke, but then again, I was never severely addicted to smoking like some people seem to be. I don't know what to tell you about going to the IL's - I think if it were me I would just tell them the truth, and then if they still refused to stop smoking around the children, I guess you have no choice but to not go. I cannot believe someone would put the importance of a cigarette over a child's health.

NOT being able to breathe. I even cracked a rib from all the coughing!
