My wife and I will be going on our first cruise in October (12 nights on the Norwegian Dream - Istanbul to Athens). We will also be spending 3 nights in Istanbul and 3 nights in Athens. We can't possibly pack enough clothes to take us through 18 days (can we?) so we would like to be able to have our laundry done on the ship halfway through the cruise. Can anyone tell me what our options are on the Dream and approximately what it will cost?
