It's good that she was able to go with her family by her side in a place she loved. There will be lots of mourning in the UK. I'm anti-monarchy but she's clearly left quite the legacy, and people that have met her have only great things to say about her manner and attitude.
I'm also anti-monarchy, but if we had to have one, I'm glad it was her :) I've never met or didn't know her, but she came across as a good person and it's odd to know that she's gone.
