We go to my Grandma's in the afternoon, do our shit there, and then come home and open presents at night on christmas eve. Then we open "santa" presents on xmas day. When we finish, I go with my dad to missouri to see his side of the family, and my mom and step sisters/dad go to texas to see my stepdads family. Not a fan of how it works, though. I liked it better before my step family when we opened all the presents on xmas morning.
