Passport America imho was never intended to be a ‘destination’ finder. I’ve always viewed it as a cheaper way to travel before Wallydocking became a lifestyle.
(In Utah I met a couple that were staying two weeks in the WM parking lot because it was cheaper for their quarter million dollar motor home to run the he generator seven hours a day. I was staying at a nice FHU PA campground nearby for $21.52 per night when tax was added. It was November, the PA Park was offering that $20 per day + tax for unlimited days.)
That’s how we use PA. I have a destination, and I break the trip down into individual days travel distances. I then look to see if a PA Park is near where I want to stop. If the stop fits in their requirements - we stay there.
I’ve gotten a four night stay in Daytona Beach FL during bike week for $20 per night because we called from two hours down the road when the previously planned stop was full. The guy said, “I’ve got one empty spot and If I give it to you for the PA rate, I can put out the no vacancy sign.”
Two parks we’ve stayed at more than once advertise as one night stop overs. They don’t want longer term folks. One on I-40 at Tucumcari, NM the other on I-10 in Benson, AZ.
I’ve stayed at a couple parks that are full of long term families and workers. They rent out any temporarily open spots. A night of two later, they would not have had a vacancy.
Because we are retired and have a lot of flexibility, we plan most of our moves for Tue, Wed or Thur. We try our best to avoid traveling on Friday or Saturday.
So we seldom find PA restrictions hinder our stays. I stayed a week at a PA park in Moab, Utah - in November.
I fully realize that PA discounts and restrictions do not fit into the travel plans of many folks, especially wekenders and those on the once a year big family vacation.
You can only know if it works for you by trying. I consider PA well used if we stay at PA parks four to 12 days a year. I don’t expect more, but am happy to take them.
My primary discount program is the federal government senior pass. My mapping software and books show federal campgrounds and I can often stay at one either for a two week destination stop or an over night. We took 10 days at USFS campgrounds dry camping near Yellowstone and Glacier NPs for avg $10 per night vice a $40 to 55 per night FHU commercial campground. But we know how to dry camp.
There is an art to shopping for travel discounts with any form of travel. We work at it. Not only for camping, but for fuel purchases, propane, groceries, etc.
