That's why you would want to get a big estate with separate houses for each family, but have them be close enough that you could easily move from one to the other depending on which night you want to spend where.
You know what? Go here [address of humongous estate with perfectly suited housing for everyone just outside of NYC]. All your housing needs provided. All you have to do is talk your people into moving in. I'll even move all their shit for them.
