Rang P and O today to check availability of special offer places and they still have £48 for two people inside cabin with en-suite if you ask for the sun newspaper special offer price (thats £24 each). its £53 for an outside cabin (window) sun special offer price.

That includes coach transfers from the port to Bruges but doesn't include any food. Car parking at the Zeebruges ferry terminal is free. You usualy have the same cabin both ways so you can leave things in the cabin and only take with you what you want for the day.
