Absolutely amazing. My wife and I and our four older children spent three nights with Sandra and had a blast. We started our trip in Enkhuizen (about an hour from Amsterdam by car) and spent the day in a really cool fishing village, which Sandra was able to get us entrance into at no cost since we were passengers of one of the antique ships. Over the course of the next three days, we sailed to Urk, Hoorn, the island of Marken, and finally departed in Monnickendam. Blessed with beautiful weather, our days were a mix of restful relaxation, combined with moments of intense excitement and energy as we sailed the boat. We also got to explore each of the cities we visited (Hoorn was our favorite) and see much more of the the Netherlands than just Amsterdam. If you have the opportunity to take this amazing adventure, understand that you will be much more than just a passenger - you are also the CREW! Our only regret was that we didn't book more days. Thank you Sandra!
