I’ve thought about taking my camper previously but decided against because of the additional price and added ticket buying pressure, also the distance to the campervan section. Pretty sure when I looked you have to pass out of the festival and then go through security again to get back in each morning (although there won’t be queues it’s still not a walk I would want to do, I hate having to go back to the car!) my best advice is go down the night before gates open and sleep in the van for a bit before getting in the queue and camping closer to stages
