Christmas- how do I get them to understand I don't want to go?

We've been asked to spend this year with family we didn't see for many many many years, who we've recently reconnected with. They invited the family to Christmas, and I don't want to go. My two sisters are HOUNDING me to go and I keep telling them no.

There are various reasons why I don't want to go. The main one is that they are huge party animals who have no respect for the fact that I don't drink, and don't want to spend forever and a day there (literally, we spend a minimum of six hours there everytime because it's all drinks and eats).

Everyone we go there they laugh at me because I just drink cooldrink (I'm sure it's endearingly but as someone who has been constantly pressured into drinking by many many people, I don't like it).

When it's time to go (because they live an hour away and we've got responsibilities) it's always, " there's no rush, we also have dogs to feed, we hardly ever see you, etc". My husband drinks so they enjoy his company more than mine because they obviously all get drinky happy.

Also, they all speak a language that I'm not great at so they all speak it (it's my cousin's home language, our second language but because I never lived with my dad, and was raised primary English, I can't speak it very well. It's my husband's second language too but he was raised speaking it, speaks it at work all the time and is fluent in it).

I'm always the designated driver and I don't feel they respect me when I feel it's time to leave. They put huge pressure on me to just let my husband have one more, etc. and I don't like that, it makes me uncomfortable and again, like they don't like me so much as they like my husband. I don't want to spend my Christmas like that.

Am I wrong?

*It seems people think it's his family. It's MY family, on my dad's side. We legit didn't see them for about 15 years and have in the past couple of years reconnected.
