I had only one full day in Amsterdam and a crammed it with three excellent museum visits.  

First I visited Anne Frank House and had another moving and emotional experience.  As a passed through the rooms that Otto Frank used to hide away with his closest friends and family I had tears in my eyes.

Next I visited the Rijksmuseum.  It has eclectic collections of art and decorative arts.  My visit was short but I enjoyed it immensely.
