Wot's it like?
-$$$ (ticket prices are great: drinks/fees, etc.)
-public transport/trains/shuttle buses
-festival food (vegan/vegitarian)
-pre-and/or post-festival sightseeing (proximity to Brussells/Ghent/Antwerp/Bruges)
-avoiding shite headliners but not having to see a boring band or being forced to chill even though that might be fine and well
-facilities (camping, baths, etc)
