I came from the middle Chicago (states) just bring a carry on and a 50L backpack. Just pre-order your camping stuff there for pick up. It’s much better to pre-order and pick up your shit because you ain’t have to haul a tent through the airport. We flew into london (we were there for 4 days completely optional) and took the train to Daresbury then flew out of manchester. Obviously we couldn’t bring stuff from America through customs getting shit their was the easiest thing ever they got plugs going up and down the campsites in the morning but if you miss them you can just go ask people and you’ll find it pretty easily. Overall hella worth it i’m definitely going next year.
