I will probably turn up around 4pm, but I will confirm that closer to the date. I don't think there is much point turning up any earlier, since check-in may not be available until 6pm.

I agree that they won't eject you from the venue if you don't have EAS, however security will be set up around the perimeter of the camping area to ensure noone without a wrist band gets in for security reasons. So, if you guys are turning up on Thursday without EAS you will have to spend a night in the car park or some other green space .
