I am under the understanding that many of the people in amsterdam speak english, partly due to the HIGH number of british tourist each year

, but also they are now taught from a very young age in schools, as the dutch language is only spoke in holland, and hardly any or no where (not sure) else, but english is, so they learn that. (i may be wrong, correct me if i am,

)
I went with a mate who is quite good at dutch, so we did seem to get a bit more patience from the people, coffee shops and other places. I on the other hand don't speak a word.......

But would like to learn someday, as i have found fom my own experiences, that knowing a local launguage does help you with how the local treat you.
I speak ok spanish and when holidaying in spain, found that speaking spanish helped my "popularity" with the Hotel staff, and they would always serve me first regardless who or how long others had stood at the bar.

which had it's good and bad points ( hang overs are a bitch

)

Peace
And enjoy the dam, one hell of a place!
