Experienced party host question!
Long story short: my stepdaughter is having a family party at our small, old house soon. She lives across the country and this location is fairly central to her very big extended family on my DH's ex's side. When we said we would host the party, we assumed it would be a fairly small group for a backyard party...like 20 people. Turns out, she invited 100 people and at least 35 are coming, likely more.
Our yard can fit that many people but we have a really small house and only 2 1/2 bathrooms. The two bathrooms are both en suite and upstairs, and I would rather not have my DH's ex wife's entire extended family traipsing through my bedroom and son's room to use the toilets there. But is one half bath enough for this big of a crowd? I don't believe there will be alcohol served, and about 10 guests will be children. What's a general rule guideline for how many people a guest bathroom can support during a party? Do I need to get a Porta-Potty? We've hosted parties of 20 or 25 several times and occasionally people have needed another bathroom, but that's usually during long-stretch family events like Christmas or times when alcohol is served. Plus they were all my friends or family, not my DH's ex's family.
