Honestly even if it is crap you’ll have such a great time. My wife was only bothered about a handful of artists (PSB, Mik Artistik, The Beths and Beans) and knew none of the headliners but she absolutely loved it.
It’s ok, I’m sure OP never goes to gigs, sporting events, food/drink festivals or any other large gathering given the disruption they cause for people.
My experience of the locals when trying to organise events in the local area is they’re the biggest load of moaning NIMBYs so I’m not at all surprised by this take. It’s four days, one of which ends early, and you have a year’s notice if you want to give it a swerve.
I really missed the old layout where you could walk around the back of the Lovell to where the old Mission Control tent was. It was also a shame that moving the Lovell stage forward meant there was less sound bleed to the campsites - it was always quite nice heading back to the tent in the afternoon for a bit but being able to hear the main stage.
My guess is the revised site was down to ticket sales. If they are back to the old numbers next year, it would be great to keep Mission Control where it is now but move Nebula down to the old Mission Control site. It would spread the foot traffic out a bit and help a lot with sound bleed between the music stages.
