Is the RV invisible?

Attempting to pull into our site at Kathryn Abbey Hanna park in Jacksonville, Fl.  There are literally hundreds of bike riders, electric scooter riders, walkers, and joggers all over the roads like confetti.  John navigates most of the way with precision until he attempts to back into our site.  There is a woman who has two very small children.  She is in front of the RV la la la having a wonderful time while her toddlers are behind the RV.  JOHN CANNOT SEE THEM! He knew they were there when he pulled forward, but now backing up they are out of the camera and John's sight.  He had to yell at the Mom "LADY! I CAN'T SEE YOUR KIDS! GET THEM OUT FROM BEHIND ME!" 

On the way to Jacksonville we hit a bit of a tight squeeze.  ​
