A 120-inch screen, a 3000-lumen BenQ 1080p projector and 7.1 surround, with reclining seats for ten. There is a full library of DVDs and Blu-rays, because the ferry does not care about your streaming plans and neither does island weather on a wet Sunday.
It is a proper room rather than a television in a basement: doors closed, lights down, the works. Expect to lose one evening of the holiday to it, and possibly the children for the whole week.
