Niantic asks us to nominate and vote on Wayspots that are Great place to socialize, exercise, or explore. I’m not sure that i understand how an RV park would match one or more of these criteria.
Unfortunately we cannot look at other in game Wayspots an assume they meet current criteria. The ones you have mentioned don’t sound like they match up or are even good quality.
Please consider sharing your nomination in the Nomination Support area before and folks can help with advice before you submit. About the Nomination Support category
