I've travelled around Europe quite a bit and have found that the lack of the native language not a problem.English is fast becoming the language Europe.A Swede will converse with an Italian in English.You're so brave I don't know how the girls do it who with little language
Glad you're having a good time in Amsterdam, don't know if you like art but the Rijksmuseum is a great place to visit.Rembrandt's The Night Watch is there.Try and watch a movie called Nightwatching first as the painting holds many symbolic meanings and the movie tries to uncover these.There's a few Vermeers there as well.I really enjoyed the gallery.The Van Gogh museum is worth a visit too.
As Nyna said, light one for me as well.
