cruise lines from Amsterdam -> UK for young people?

Another point to bear in mind - you cannot take your own booze on board - bags are searched before boarding! Possible to buy wine in the shop to drink on the return trip but not the first night as it isn't available until the morning! having said that, the bar price aren't bad anyway. We have travelled on these boats many times and out of season, especially in the week, things are usually very quiet and dull! So pick your time carefully if you don't want to be accompanied by retired couples like us!
