Overstimulated around in laws - help

So backstory, late 20s, been married for 5 years. My husband's family is very close knit and spontaneous. Mine is very much not; dysfunctional and emotionally distant and visits are time boxed and pre-planned.

My husband is happy to spend an entire day with family morning until night and over the holidays often several in a row, they do hobbies together and it basically all revolves around the whims of his dad. I get very uncomfortable and overstimulated and want to have time alone since it's 10 people and very loud. I don't share any hobbies or interests with his family although we get along great. We live across the country so stay at his family's place when we're in town visiting.

Basically without fail after 48 hours I feel boxed in. My husband says I am free to do whatever I want, but since his family does everything together I look like a recluse and his dad comments on it constantly.

Tips on how to handle??
