I've participated the last 3 years... and really enjoyed it. I like the whole concept of exploring…read moremuseums and venues at night, with music and food, and lots of people. I ended up visiting places I hadn't even thought of because it's included in the ticket.. and some were really fun to experience. Each year is a bit different, so I've been dancing in a crowded museum, ate some ethnic food, admired art, played around with interactive parts, or just walked around... If you're in Amsterdam during this event, you should go!
