Ferries are pretty nice, we recently used them for a NL -> EN -> WA -> IE -> SCO -> NL trip and they were nice. Some of them had plenty of entertainment and felt quite nice, others a bit more run down but still fine. The best was taking the overnight ones, you sleep on board and disembark fresh and ready to go in the morning at your destination and costs less than having a separate hotel night.
