Baby shower question

My mom wants to throw a baby shower and my mother in law wants to throw one. They would be co-ed. My husband and I thought why not just combine showers and have one shower and have it at our house so it’s a mutual space. If we combined it would be about 70-100 people. My mom and mother in law are fine with combining, they said whatever I want we can do. I’m torn on what we should do. Having one with a lot of people or breaking it up into two smaller ones?
