After returning from a Panama Canal on the Maasdam, sorting thru upcoming cruises the 32 day explore South America Passage and Inca Discovery was of great interest. Fortunately for future travelers, the Zaandam is going in to dry dock to be rehab in 2018.
In the Lido dining the chair cushions show great ware as they are sunken in. There was very little variety of foods from day to day. No specialty nights with native food from the country we were in. Randomly closed parts of each food line thus had to go from side to side to complete a meal. Food became 'same-O-same-O'.
Internet very expensive, very slow, basically non functional. On some other cruise ships, internet is free. Waste many of your minutes waiting for it to connect.
Was offered an upgrade to Vista suite (for dollars) took it because 32 days in the bottom might just be too much. Glad I did, And now I will only book suites ever though they cast more. Deck wise, I was 1/2 between Lido and Promenade about 2/3 down the long hall. Excellent location. Up back stairs to Lido, down middle stairs to Front Office, etc.
