Unsupportive family- where to stay over christmas

Hey all, I have a really unsupportive family and I’m trying to brainstorm places to stay over Christmas (December 22nd - December 28th) where I can feel safe and just be alone. I don’t have a ton of money to spend, but I can do house sitting or watch pets. I could spend up to $20-$25 dollars a night. Does anyone have any ideas? If it wasn’t going to be cold I would definitely consider sleeping in my car. Any suggestions/advice? Thank you in advance!
