how to handle in-laws who smoke

Hello ladies!

I have a bit of a dilemma and I don't know how to tactfully approach it. 

My in-laws smoke. A lot. Like, several packs a day. Whenever we visit them, you can barely see because the smoke is so thick. The smoke has always bothered me, but I want to avoid second hand smoke altogether now that I am pregnant. Luckily, my husband and I have been so busy, that we haven't had a chance to visit them lately. However, I am starting to feel anxious about the upcoming holidays, when we will be visiting them in their homes. 

Is it polite of me to ask them to not smoke indoors when we visit? My husband suggested we have them over at our house (smoke-free) for the holidays, but I already know there is no way I will want to play hostess for Thanksgiving or Christmas. I feel like asking someone to not smoke in their home is crossing a line and I don't want to cause any discomfort. 

Any advice will be greatly appreciated.

Thanks!
