Most of the time we either go to my MIL's or my dh's grandma's. For my folks, it's always at my mom's house, because it's just them, us, and my brother & his wife. I live 3 hours away, and my brother has cats that my mom is allergic to, so it's pretty much no-contest...

I have had a few little get-togethers at my house, and WOAH...it takes some time to recover from that!!
