Be aware that on August 21 2010 the ship will NOT dock at the regular cruise-terminal in Amsterdam.
The big 5-yearly event Sail 2010 takes place and tall ships will take over the dockingplaces in Amsterdam.
Your ship will dock at an alternative place - Ceres Terminal. This place is about 10 miles west of Amsterdam.
So check with your cruiseline re transfers to that dock.
Have a great cruise.
