Well, originally I was imagining all of the fine platinum and gold trim that frames the doorways of my super-baroque stateroom. I was thinking that the light fixtures, mirrors, and vid screens were all probably framed with very expensive decorative--word-loss: what do you call elaborate, lace-like, metal work done for decorative purposes--accents that one could easily sell.
As for the furniture and delecacies themselves, I would be more worried about a crash situation. If a ship must be abandoned, or all hands are lost, I imagine that the absolute best, first class staterooms would automatcially seal in an hull-breach emergency. Both to save the wealthy passengers and their goods.
Think of it as a more frivolous Star Viking operation...Your party cutting into a century old stateroom, as they take in the decadence of the Golden Age of the Imperium, a bottle of two-hundred-year old Terran wine floats past, along with the floating bodies of the two nobles who sat and drank in the stateroom, waiting for rescue until their back-up life support finally cut out.
