Miricle, Zuiderdam, Volendan, and Zaandan. There is also the Raddison ship and a Crystal ship but that ship is private chartered. The first four are the ones that you can board for a price for either breakfast $21pp, Lunch $32pp, or Dinner and entertainment for $299pp. Too rich for my blood! There is also supposed to be a package that you can stay onboard for a night around $599pp.
