Hello. We are going too and a few other mn ers. We have a camper and will be alone Friday then dds 2 and 11 coming for the rest if it. Website helpful but so was the phone line. It's not glasto so you will be fine. Not been before but I've heard nothing but good.
I've been past two years but we can't make it this year. Camping area can get busy ime. If you can arrive Friday I would do so personally, although the queues to get into the camping area can be a pain. But you'll get a better pitch.
Food was fine iirr. We didn't cook at all.
Very safe for children. Your two would be fine to walk about the main festival area without you tbh. Lots of child friendly activities too, more your 9y's age range I guess though.
You can drive to the camping area. You then need to drive car back up to car park once unloaded. The getting to pitch is where the queues happen and it can take a while to get round. Mind, I think they're opening up Earlier this year which may help matters
