The Volendam was chartered on this cruise by Atlantis Events, a US based gay and lesbian travel operator, and timed to arrive in Sydney on the day of the Mardi Gras parade. Accordingly, I haven't included any comments about entertainment as this was specific to this cruise.
Summary: an acceptable 4 star experience (even though my comments below look more critical than that) but overpriced for what it delivered.
Cabin: we had a verandah cabin. It was spacious. It was well kept, though clearly showing signs of age. It must be said that the ship needs a refurbishment. This is not to say that the cabin was unpleasant, however for the price (USD$3,350 per person plus the USD$11 per day per person service charge) it did not present good value or an exceptional experience.
Standard verandah cabin, but well towards the back of the ship. Next time would choose more midship, but this wasn't available on this cruise.
