We drive an hour to my Grandmother's and have a huge dinner with my family and exchange gifts. Christmas day get go to my MIL's house and do it all over again with my husband's side of the family. Luckly we draw names on his side of the family to exchange gifts between the adults - all of the children get gifts from everyone. :)
We don't have any kids but I have 7 nieces & 1 nephew to buy for. My dh's family draws names on Thanksgiving for Chrismas presents so I always have those two people to buy gifts for, and of course at leatst one thing for me!
