So there will barely be an entry fee for people coming for the day too. For a measure targeting people coming from thousands of kilometers away, I do not see how this is even going to make a dent in the tourist influx.

Looking for relatively similar cases like Machu Picchu or Tanzania national parks, I would have expected a fee between 50$ and 100$ to curb the tourism.
