That said, after thinking about it for a minute, the devil may be in a lot of details here.
I've been to past free photo hot-spots that were beyond crowded and impossible to have any breathing room in, in complete disrepair and borderline-dangerous, dirty, no amenities like a restroom or water fountain, no parking, etc. Having a relaxed time trying to take an amazing picture and enjoy the view was impossible.
Some kind of fee to facilitate a special experience doesn't seem too unreasonable, though the price point mentioned seems far beyond reasonable unless the experience is truly luxurious and first-rate.
