The four of us, who are not into big partying, will be in Amsterdam April 28 through May 1. We plan to see the Anne Frank House, Rijks museum, Van Gogh Museum, Keukenhof Gardens, and Haarlem. How would you organize our itinerary with Queen's Day falling on the 30th? I was thinking about going to Keukenhof that day to avoid the worst of the crowds. Would that be wise or would it be better to avoid public transportation and just stay in Amsterdam that day?
