My friend & I have cruised on Holland America around 155 days.
We found the Zaandam to be updated since our previous voyage on the ship. The rooms, services, meals and activities were all we expected.
We enjoyed the Culinary classes and demonstrations. Especially the hands-on cooking class for $29.95. One of the chefs, Sander, taught us how to make 3 different dishes. Afterwords we went to the Pinnacle for lunch where they served the same menu we had just learned. Lively conversation between classmates as we shared our foodie & cruising adventures. The lunch included your choice of a very nice chardonnay or red wine, which I heard was also good. This cooking class is not advertised, you need to go to the front desk and ask for the "hands-on" cooking class.
Very nice location. Typical HAL Room. Had a bit of a problem with the air conditioning not cooling enough, but they promptly looked into it and fixed it right away!
Staff at our hotel, Puerta Escondida, recommended some lovely activities such as riding a funicular (ascensor), paseo atkinson, and walking various colorful passageways. They also recommended wonderful restaurants that we loved: Fauna hotel and Pastevina.
Took the train from Valparaiso station near Plaza Sotomayer. Got off at Mirimar station and walked to the flower clock, and around the coast near Wulff Castle. Stopped at the Sheraton for drinks and a snack before walking back to Mirimar train station.
Wonderful transfer from Valparaiso hotel, 100 miles, to Santiago Airport with wine tours and lunch (we paid for our own lunch).
