Can't do Christmas because of smoking MIL - Rant

Sorry - Coming to terms that we are going to miss our second traditional family Christmas in a row because of my MIL'S habit...

I'm due November 25th, we live 6 hours out of the city where both my husband's family and my family live. We usually go to the city to spend holidays with our families... But we usually stay at my smoking mother in laws house... Which wouldn't work this time around. And I honestly don't know if I will feel put together enough to drive 6 hours with my husband, 1 month old, 2 pets (who are family and will spend Christmas with us no questions asked) to get squished into my sister's unfinished basement (no bedroom) with a cat, dog and new baby because it is the only non smoking accommodation we have available. But we missed Christmas last year due to my husband working and am bummed that baby's first Christmas may be spent away from family. If we had people come here... We have two spare bedrooms where we live which would have to be cleared out somehow to make room for two groups of people to stay... But doable for two and two only. No basement and we won't keep people in our living room as it is our main living space. Also - Most of his extended family can't drive anyways so it would be parents and maybe siblings at best if people came here. Though we still only have two bedrooms to host... Not that I am hopeful anyone would make that drive to see US.

I'm mainly grumpy because everyone is pushing us to come down so they can see baby...Which I don't give a crap about - I will do what we want and feel prepared to do no matter what... but I DO want to do our usual big traditional family get together. But the 75% of the reason we CAN'T is because my MIL smokes in her house (the other 25% being just the long drive with a new baby that is breastfeeding and 2 animals which may not be an issue if the length of stay makes it worth it). If she didn't we could stay at her house like she wants with our baby and 2 pets in her freshly reno'd basement. Christmas dinner is almost always hosted at her place so we wouldn't need to worry about commuting again for that. Instead if we go down we have to find non-smoking accommodations, piss her off in the process, probably leave our pets in a kennel because there is no space in non-smoking accommodations we have available which breaks up our little family, contemplate if we should even BRING baby to the Christmas gathering because of her smoke smelling house.. Among other things. But it is OUR fault we are considering not coming down for Christmas, and we are being stingy and selfish with baby even though we would desperately like to make it work... 😒
