My mother-in-law is hosting the whole extended family this year--28 people in all! It's so many people and everyone is in town for 3 days (staying in nearby hotels), so it's not just one meal. So this year she is focusing on making it easy on herself. She is going to get the turkey from a caterer--I think there's a turkey farm near them that provides cooked turkeys as well. We will all contribute the side dishes, since there are so many of these that are special recipes we'd be sad to not have them. It seems like a good middle ground.
After all, Thanksgiving is supposed to be about giving thanks and being with family and loved ones anyway, right? So if this is what you need to do to enjoy your time, I say go for it!
