If 47 is too may people to risk, 3 or 4 are? My point still stands. Is your point that it should always have been shut down, or that it should be limited to just a few people each visit?
3 or 4 are a hell of a lot less potential fatalities and a hell of a lot easier to evacuate. Sure - I'd be okay with reducing access so only a few could go - better than closing it down entirely - which is what i expect will happen.
