I think she may have worried about her safety going, given how harassing these people were. Also she may have felt that she now wouldn't be able to look for work because she's given a commitment to these people that she would be going, whereas usually actors say that if they can they will be there.
Yeah I would have loved to have met her. On balance I can understand her decision although it is a bit unclear just how sinister some of those internet messages were or even if the people saying they were going just to see her were doing os as generally fans, or because they had a bit of a screw loose.
I only found out that Eliza was over here after it was over (not that it would have made much difference as the tickets all sold out months ago).
Would really have liked to have gone.
And the really gutting thing....I was only half a mile down the road for two of the days she was there
