I am just off the Zaandam 4 weeks cruise. I consider myself an expert in the ice cream served on the Zaandam. At the end of the Lido buffet toward the middle elevators port side they have ice cream at lunch and dinner. Also cookies and other deserts. They also had a soft serve machine at that location. Usually only one choice of soft serve. But, they had multiple choices of ice cream. They occasionally have a sorbet. One day they had an ice cream social at the Lido pool area around 2 pm. No ice cream at the late night opening of the Lido. Hope that helps.
