When you build a lazy river, you seem to need a lot of life guards and they tend to have a large forward view. Might be kind of nice if you could set a lifeguard to patrol between two points. The longer the patrol, the lower the safety rating. This way you could get more coverage with less lifeguards.
- It's hard to tell what's the appropriate depth for a lazy river. Is it wading or swimming? I always felt like you could stand in a lazy river. Maybe this is a bug or I need more shops, but I feel like I never see the guests float in a tube. To this, maybe a toggle to enforce pool floats.
- Change the flow speed of the lazy river.
- Have water effects (waterfalls, etc) that impact the excitement, not just scenery score. (maybe it does and I'm not realizing it)
- Mounted squirt guns that other guests can spray the people in the pool floating by.
