Be careful, you might accidentally learn something - Wendelin is THE man! The tour is laid back and everything is as they convey when you book ... look for the white umbrella at Dam Square, check in, get a load of fun for the better part of 2 hours. To be honest, before we left it became clear that Wendelin was somewhat of a history expert on The Netherlands. I'm predisposed to not care much about history, but Wendelin inadvertently flipped my understanding of my own interest in history. We did the walking tour early in our stay, and I didn't know until the next several days just how lucky we were to have bee on his tour ... when we were simply strolling around and paying attention or on a boat cruise or in the Rijkmuseum, we found ourselves numerous times saying, "Yes, remember Wendelin told us about this?" (e.g., William of Orange, William the second, Louis Napolean, architecture, coffeehouses, bicycles in the canals, keeping your fly zipped if you drown so that they actually do an investigation, etc.). I love London Walks in London, and Free Walking Tours Amsterdam is just as good. Highly recommended. (attached photos are poor, but I think that's because we were listening rather than photographing.)
