Just back from the Zuiderdam August 5th and I remember the prices of drinks. It was around $7.95 for a glass of wine, drink of the day was $4.95 and domestic beer was $3.95. We tried all of the drinks of the day and they were quite yummy. The ship was very nice and easy to get around. Don't forget your binoculars you will need them. Also it rained almost everyday. Bring warm clothes as you probably already know. It was 40 degrees at night and our warmest day was 70. The ship's crew were very nice. I would have preferred more up to date music. I thought the activities were geared toward an older crowd. We had a great time, I hope you will too.
