Van Gogh Museum, Amsterdam
I wouldn't consider the museum as tourist trap, but you should only go there if you like Van Gogh's Art.
Unique Suggestions: Check out the famous paintings.
Fun Alternatives: There are a bunch of other museums in Amsterdam to visit (Historic, Anne Frank House, etc.)
This isn't a tourist trap per se, but I was bored. The pictures are all there, its well run, though some of the teenagers can get loud. I thought it was more expensive than it should have been and the audio tour for my wife, in Japanese, was incomplete, plus, she had a hard time working it.
Unique Suggestions: Avoid pointing at the pictures, the iron-legged guards yell "Distance" at you.
Fun Alternatives: The naval museum is awesome.
Besides RLD, this Van Gogh Museum is another place where I was seriously Trapped, entry at 15 guilders for adult, although I tried hard to act like a small kid but fail, anyway it's a big trap...lol
