Large family maxing out our budget

Hi everyone! My fiance and I are really struggling with planning a wedding, we both have huge families (direct family and first cousins makes up 165 people) and with our friends, our list is closer to 200 people. How have you all cut your lists down? We currently aren’t inviting anyone under 21 and cut out a large portion of our friends.

We’re also on the search for a wedding venue in MA. Any recs that lean more budget friendly?

Thank you for your help!

Edit: editing to say we’re also open to less traditional wedding options as well! We’ve just ran out of ideas

Editing again to say: THANK YOU to everyone who responded. This is my first time posting and this thread is so helpful.
