I am at my in laws and we had a huge family dinner last night. I am now expected to go to a huge family brunch immediately and then stay all day at another family member's house, then go to dinner with friends, then wake up and go to a huge event. I am an introvert. I am laying in bed dreading getting up because these are the last moments I will have to myself today.

What are some good ways I can try to sneak off for alone time so I don't go nuts?

Ps don't worry. My MIL left a copy of The Guide to Jewish Interfaith Family Life by the bed for me. Even though I converted.

Eta: thanks for all the great suggestions! But holy shit my FIL just knocked on the door and told us to get downstairs because company arrived. Who? What? I thought I had another half hour. Aaahhhhhhh
