I have really been enjoying the Summer Update items! One thing I have been noticing is having food (ice cream) and drink (coffee) options available outside causes guests more immediate bathroom needs. This also happens when they are out enjoying the al fresco exhibits, which can come with the trait "Squits & Giggles." I would love a way to make an outdoor bathroom of some sort even if it does require a small building. But right now, making a building with just a bathroom in it is kind of silly and doesn't make sense as you would need the building entrance/exit and the bathroom entrance/exit.

When I saw the Summer Update, it made me think about Porta Potties and how that might provide an option for guests outside. Maybe the guests wouldn't appreciate the Porta Potties nearly as much, they could have poor decor, but it would help the flow within the entire museum.
