Repositioning is, when the cruiselines bring back the ships for the winter for example from Europe to the Caribbean or in the spring from the Caribbean to Europe.
You also have repositioning cruises from Alaska to Mexiko or Caribbean. These cruises are normaly cheaper.
And yes, the price I wrote, includes airfare.
But my hubby tells me now, that the difference between Euro and US $ is not longer that big. So its about 15 % less in US $ than in Euro.
