Just found out about this event in the UK which this year is being held in Bristol.

If you book before the 31st May you get cheeper prices.
And.....
The Linux Expo being held at Birmingham is off - according to the website.
This is the second time it has been cancelled, I understand that new organisers were brought in for the second event quite recently, and obviously things have not been going too well for them.
