many long years ago - did one just for the MK - it was a behind scenes thing - they took us under the tunnel, to where they process the water, the plants they kept so they immediately have one when one dies in the parks, bunch of stuff.
so don't know what this tour has in common with that one.
you went behind a bunch of stuff - most of time camera were not allowed. but in the gardens where they were training the plants it was.
