"I'm sure they would prefer to take their time and stroll around amongst the stones and not be herded around a rope or whatever they are now planning."
Well again you seem to be saying reduce numbers so the erosion danger is less so people can go inside the stones and have a better experience.
Lucky them but what about the ones that are turned away to enable this uncrowded experience to be enjoyed by the minority? How would you select them?
No foreigners, no Gingers, no Northerners..... ;)
