Found this in different threads, written by Danmeister (it's about 2011, but guess it's not too far from the facts this year):
"In 2009 Graspop Metal Meeting launched its now famous Boozebag concept: only available in presale, each bag consisted of a number of tokens that paid for both food and drink.
Three years later the Boozebag has become part and parcel of the Graspop experience.
A Boozebag still costs 50 euros and the 22 Graspop tokens inside will buy just about anything on sale in the festival arena, be it beer, soft drinks, French fries, pizza, etc.One Graspop token is worth 2.50€.
Just to give you an idea:
* one beer or one soft drink: 1 token
* Metal Market entrance fee: 1 token
* Festival programme: ½ token
* French fries with sauce: 1.5 tokens
* Breakfast package: 2.5 tokens
Graspop tokens are just 2.25 euros when bought in advance as opposed to 2.50 euros/token on the day, so you don’t need a calculator to tell you why you should order a Boozebag today.
Also, the content of the boozebag will be slightly different this year. Apart from the 22 Graspop tokens, you will also receive a stamp card that you can use to collect a wide selection of fun gadgets as well as a few free drinks from the sponsor stands dotted around the festival site.
The Boozebags are sold as vouchers with a unique barcode that must be scanned at the box office on the day. If the bar code is valid, the voucher is exchanged for the Graspop tokens and the stamp card, which will enable you to collect the gadgets from the various sponsor stands.
We’re extending Boozebag sales to give everyone ample opportunity to make use of this unique offer. Still, don’t wait too long because the offer is only valid until 16 May... "
"The official t shirts have been €20 since 2008 when I started going to Graspop"
"The charging points just have lots of different phone adapters, so there isn't a place to plug other things like cameras"
"There is no early entry. The campsite opens for everyone on the Thursday before the festival. It usually opens around 2pm. "
"About 75 bands attend Graspop each year."
"The festival is in Dessel Belgium map
. I normally drive over, and I get the ferry over to France. Norfolkline
is normally the cheapest, it does take a little longer than the ferries to Calais, but it goes to Dunkirk which is nearer Belgium. From the Isle of Wight it takes me about 12 hours to get there. " TRAFFIC DISRUPTIONS ON THE E34 MOTORWAY
Traffic may be slow between the motorway exit and the festival site if you’re travelling by car via the E34 motorway (Antwerp or Eindhoven). There’s a diversion as the centre of Retie is closed to all traffic.
Fans travelling from the direction of Eindhoven should take the number 26 exit (Arendonk/Retie) and then follow the signs for GMM.
Fans coming from the direction of Antwerp should take exit 25 (Oud-Turnhout/Mol/Retie). SHUTTLE SERVICE BETWEEN MOL STATION AND THE FESTIVAL SITE
The shuttle service organised by Flemish public transport operator De Lijn takes festivalgoers from Mol station to the festival grounds and back. The only pick-up/drop-off point for the shuttle buses is right across the main entrance to the campsite/festival arena. Guests staying in Graspop Metal Town should also get off here. GMT is a 15-minute walk from the bus stop.
All ticket holders can use these buses free of charge. It’s approximately 20 minutes from Mol station to the festival site. NO NIGHT TRAINS

More and more festivals are being targeted by pickpockets. Protect your valuables and do not put your wallet in your back pocket. PROTECT YOUR EARS
Graspop Metal Meeting respects the applicable noise level standards. Thanks to the use of high-end equipment, the sound quality is first-rate and the decibels are kept to an acceptable level. Still, ear protection is always a good idea. Free ear plugs can be collected from the info desk and the Proximus stand. "
