Our holiday plans have become much easier in recent years, thank goodness, so now I am not nearly as stressed trying to accommodate everyone and everything.
My ILs have started going to Florida over Thanksgiving week (which also includes their anniversary) so we have Thanksgiving with my family at my sister's house. Our holidays are always potluck that are 'assigned' to you by the hostess, and they always start with food ready to eat at noon. I made green bean casserole today, and I've asked to make my mom's famous broccoli-cheese casserole (I could seriously eat the whole thing by myself in one sitting!) for Christmas. We decorate my parents' house for Christmas sometime over Thanksgiving weekend, and my mom and I take the kids to see Santa at the mall, too.
We go to my mom's church as a family on Christmas Eve and then back to their house for snacks. I sneak out to go to the 11 pm service at my church and wrap presents in between times by the glow of the tree & with my Spotify Christmas playlist going. We go back to my parents' house Christmas morning at 10 am for presents & Christmas dinner. Everyone (kids to adults, adults to kids, and adult to adults) exchanges presents, and the kids get gifts from Grandma and Grandpa and 'Santa.' My mom's love language is gifts so there are always lots and lots.
Now that my stepson is too old to believe in Santa, my husband just always takes him after Christmas. With all of his activities and sports, it's difficult to get him for a whole week. This year, it looks like we will just have him over New Year's weekend. We usually celebrate with my ILs the weekend after Christmas but since that's New Year's this year, we'll probably do it the weekend before. Their holidays are always made by MIL who usually pooh-poohs help, and although they start at noon, we don't eat until 2 or 2:30 pm. The ILs have twice as many grandkids as my side does so each kid gets 2 or 3 things, and that's all. The adults don't usually exchange gifts.
