Ours is attached to our house. So not taking away a property. We rent it half the year peak seasons and open it up to use ourselves the rest.
We include everything you would want , I think. But I only mention things like baby equipment ( which is stored elsewhere if not needed), and other large things there like bbq/ beach stuff. Otherwise people would complain that there wasn’t a picnic ice pack mentioned or something minor, ie if last guests took it with them and I hadn’t time to replace.
check out is 10am, check in from 3pm. People still leave late and arrive early. I need those 5hrs to properly make sure it’s all clean and ready. So I couldn’t make check out later. It’s not just basic cleaning, but restocking everything, outside spaces, fixing issues or repairs. less than 5hrs is tight.
It depends on where you live, but our most spoken about items are the herb and fruit and vegetable garden. And the outdoor equipment like beach umbrellas, beach toys, picnic coolers etc that we leave for guests to use out and about.
We also have other kids basics like board games, garden swing ball, chalk, aqua water play set for summer etc.
We also have an Ev charger which is used now by around 80% of guests. I assume even more over time so I would definitely look at installing one.
