For cheaper tickets to Madame Tussaud-Dam Square, don't get your tickets from the door. You can save maybe 3-4 EUR if you buy them from one of the canal cruises office near the Centraal Station. Guess it's called the Holland International Cruise....
Getting to know Amsterdam
... start with an extensive tour of the city. You can do this by bike, by boat or by foot. Or you can take the Holland Experience. This is a 30-minute 3D video tour of Holland that you can watch sitting in a airplane seat on a moving platform. I haven't done this my self, but it looks and sounds as a great way to start your trip!
Meet Freddy Mercury, Marilyn Monroe or even the Dutch Royals! Or just take a photo with you and James Bond or Tina Turner.
While walking, I noticed many sculptures and, unfortunately, I don't know Dutch so I don't know why many of them exist. I was able to ask my "guide", Vince, about this one. It sits across the street from the Heineken Museum at the start of a biking path. It is a memorial to 30 Dutch men killed by Nazi occupiers on this spot in 1945.
There are many coffeeshops in Amsterdam. The signs are usually neon lights with a coconut tree and very colourful. These are not places that only sell coffee, but more than that. They have menu for different types of "herbs", such as Cannabis, for you to smoke.
I am a non-smoker, so I did not enter any of the coffeeshop cos the smell from outside already puts me off. I will never forget that strong stench.
