Tomorrow is Queen's Day. Although I'm currently out of the Netherlands, I've experienced this city-wide party quite a number of times, and each year I've become less enthusiastic about attending. Last year, in fact, I huddled in my apartment working for most of the day, after a brief morning stroll. But it's important to be positive, too, so I do have advice for some of you more enthusiastic participants.

One, bring lots of change to pay for the toilet. There are more toilets available for use in Amsterdam on Queen's Day than any other day of the year, but you also have to pay about 50 cents to use them. It's probably also a good idea to bring interesting conversation partners or at least a book, since you'll be waiting at least 30 minutes to use the toilets every place you go.

Two, be prepared to have beer poured on you. No matter what happens, you will return home with beer in your hair, on your clothes, and squishing in your shoes. There's no way to avoid it.

Three, learn to enjoy the crowds. The fastest possible gait is a shuffle, so you'll be getting very friendly with a lot of strangers in just a few hours. Who knows? Maybe some of the world's best relationships have formed on Amsterdam's late April streets.

Queen's Day is a rocking party, after all, and the energy of the day will get you through. Take lots of pictures, too - if you're a temporary resident or visitor, you'll never see anything quite like this again.
