Thanks for the help dude, all help is appreciated..
I'll be arriving in rotterdam on Saturday morning, luckily my bus drops me off right outside the central station so I should be able to see the building. I hope I can put my baggage somewhere during the show... dont fancy carrying around a big bag of clothes around aswell as my electrical goodies, I'll have to email the organisers... Or could I goto the hostel... book in and perhaps put my gear in a locker or something.... someone with hostel experience please fill me in here :-)
