That is a sensitive messaging campaign, and no doubt true as well. But the effect is that rich people who want to visit on the weekend will book a local hotel stay rather than day trip, and as a bonus they will not have to deal with crowds.

I think that's an edge case that would get removed if it had significant use.

Especially since the article gives me the impression you're still supposed to leave pretty quickly on those Sundays, that it's more like an easement than a day pass.
