Ticket was ~70€ for weekend pass + 25 for camping if im not mistakin.
There are free shuttle busses from Ghent, Sient Pieters (~10 (guessed) minutes to the festival area). When arriving at the main station in Ghent you cant really miss it. (Let the other ravers lead the way

Afaik you can also go from further but you have to pay for these.
Last year we took the plane to brussels and then the train to Gent which worked perfectly.
Theres also a small shop in Ghent for food and some small things just on the other side of the road.
PS: You can thank me later for that

Hail the bacon & egg bread

Catcha there
