I was in Amsterdam for ADE (Amsterdam Dance Event) and attended a 6 hour Tiesto show at the Ziggo Dome. The organization of this massive complex is amazing. Everything is clean and well organized. To purchase food/drinks, you go to a token machine that accepts credit cards, then use the tokens at the food stalls. Even though this was a massive party, everything was kept extremely clean and organized, which is a testament to both the Ziggo Dome and Amsterdam as a whole.
Excellent and huge music venue that never feels overly packed. You need to buy tokens for the bar and there's no refunds so don't over buy!Watch out for the dodgy taxi drivers - always ask how much it is and if it's too much, don't be afraid to ask a different cab down the line!
