Lu hi Yup - same here - mine are all 12 hour shifts ( some nearer 13 ) plus have been advised 45 minutes from park entrance to actual venue, which means I will be leaving my accommodation ( floor of friends house in Essex !) around 4.30am for a 6.15/6.30 am start. Also cannot find any info on why we are required so incredibly early or about proper breaks, only half an dhour for a 6.5 hour shift - OUCH !!
