Okay, my wife and I (mid 30s) booked a hotel room in Amsterdam (Joordan area) for April 29-30th. I've seen ads for private parties for Queen's Day hosted by restaurants, namely one at the Royal Cafe (Zuiderkerk). Are these parties worth the price? Any other suggestions for an organized event, or do we wing it. We know little to no Dutch, we're only hear a short term, returning to the States next month, but wanted to join in the fun and craziness of Queen's Day in Amsterdam. Thanks for the advice!
