I’ve seen lots of people say picnic areas are good for waystops so I can’t understand why this keeps getting rejected. It’s a circular area for 6 different picnic benches and tables in the middle of the countryside walk along the outskirts of a housing area.
I had a picnic table nomination in a business park that I struggled to get ML to accept. In the end I had to appeal it and the appeal was successful. ML appears to attribute sufficient weight to the social function of a picnic area if its physical form is uninspiring.
Picnic areas can make for great Wayspots, and there is even clarification on them here:
I also agree about giving it a better title/description. Including something in regards to where it’s located may be helpful in the title and/or description. Here’s an example of one that I got approved last November:
You may want to consider including the name of the housing area or the trail in the title/description, to help it stand out. Just from the screenshot and looking around on Google Maps, this appears to be around 52.04776108932203, -0.8418257450128146 at the Fairfield Play Park; there’s an image for the park with similar picnic tables on Google Maps, and I think I can see them on satellite and Street View as well.
