While we await an official release of information, the cooling has been on the event's Facebook page since around 6pm today:
For anyone that has bought their tickets already, these will obviously be valid for the revised dates and we look forward to seeing everyone a week later than originally planned. Anyone who bought tickets between the 5th November and 1st December 2016 and is now unable to attend the 2017 event due to the date change has until the 28th February to request a full refund on their tickets. Details have been sent to all ticket purchasers to let them know how to do this.
We’re so very sorry to have to make this change but unfortunately it’s due to factors outside of our control.'
