This was my experience as well. She looks much better in real life as well. She had queues of people waiting to speak to her, but she didn't rush anyone, and she'd endless patience with the questions. It was quite funny/sad - Catherine Huntley was nearby, while I was waiting to speak to Alison Young... she was also very nice - smiling and patient, even though she didn't really have a queue at all.
I know it's part of their job, but with long days of doing this, the mask (if it is a mask) didn't slip once.
