I have to defend Werchter.
Ticket price is 266 euro, no further costs. Camping is 30 euro, no further costs.
Inmusic is 94 euro plus fee. Caping is 33 euro plus fee.
Still a great difference, but not the difference you mention.
You can get your bracelet on Wednesday when you stay at the Hive, Hive resort or Hive Myspace.
The other campsites aren't open until Thursday, so we have to get our bracelet at the main entrance.
So calculate some time for that.
Staying at Camping A1 you can best park at parking A8. It's not possible to reach it from the east. There is the village Werchter and it's closed from that direction. You have to go to the village Haacht, from there you will be guided towards the parking.
At camping A1 there is plenty of space, depends where you want to drop your tent. From the back of camping A1 we usually walk about 25 minutes towards the festival area. So you probable will be in time for Fontaines DC.
Price for the Hive parking is 20 euros when you arrive on Wednesday, 15 euros when you arrive on Thursday.
You have to pay cash and if you wanna leave the parking for instance on Saturdaymorning and come back a few hours later, you have to pay the parking fee again.
