We're abandoning flights this year and doing the ferry to france thing for the first time. What sort of accommodation/seating is best travelling with kids? If it's a short journey, can you just pick up general seats on the ship somewhere? Are cabins really necessary? Also, where is the best website for cheap prices or are they all the same - I'm feeling totally bogged down by cheapferries.com / aferryto.com etc etc.
Any old hand tips welcome!! Thanks
