Welcome to the forum.
If this is a single family private residential property (SFPRP) then anything pinned there is specifically ineligible:
Forum members cannot find your nomination to vote on it.
Pinning a point of interest away from the actual location is considered abuse.
Would you like to tell us what you submitted as the focus of your nomination so we can try to help advise you whether it meets criteria? Or show us screenshots of your contribution?
I applaud you for wanting to make kids happy. But that is not a Wayspot criteria.
