I like spot 1 because it looks like its close to your river/pond. That makes a cool camping atmosphere.
I'm surprised you're the first person to say this, it took me a while to figure out what the difference was too lmao. I think spot 2 is one square to the left of 1 and 3 is one square up from 2? I'd go with 2 or 3 so there's more space around it to decorate with trees and whatnot. But it really depends on what you plan to do with the areawhat
i dont rly see a huge difference. just put it wherever it fits in nicely with the stuff around
