I call it "little brother of Tomorrowland". The oldest EDM festival worldwide is located in Haarlemmermeer where you can go easily by train and by shuttle busses. My friends and I bought the tickets online only two days before the festival. As soon as we arrived we were flashed by the amazing stages, the funny costumes people were wearing and the big amount of GLITTER. :-D After 7-8 hours of dancing and exploring the different places there we took the train back home to the Hague. My personal highlight was beeing in the first row in the crowd while Hardwell was playing. It's an amazing place to be and I will come back! :-)
