The worst part was having to be at the studio for 7.45am on the day. We stayed over but it is still an early start. Filming began about 12.30 ish I think.
If you do go and watch it be filmed, aim for the 4.30pm filmings as they do two episodes then, and only one at the 12.30pm time slot. I would say it took just over an hour for each episode to be filmed.
