"Surely people don't want to stay in that building all day"
Of course not, but the point is, it's not the *same* people is it? We couldn't arrive until after the middle of the morning talks, we went for a breath of air after the afternoon concert, and then ate in the CSH cafe, so we were only ready for the session after 5:30 ...
There's no onus on people to go to everything, but when people have travelled a long way to be somewhere, they are often quite happy to stay put.
And I'm not heaping criticism on the VW day here - I'm talking in general. If I go somewhere for a day of events, I like something - no matter how low-key, to be going on most of the time.
