What does POSH means in term of cruising?

In the context of cruising, "POSH" refers to an acronym that stands for "Port Out, Starboard Home." It is believed to describe the most desirable cabins on a ship, which were located on the port side when leaving England and the starboard side when returning, thus providing better views and more protection from the sun. Over time, the term has evolved to signify a luxurious or upscale experience associated with cruising.
