I note the word "display" above. It seems to me that 1) The starliner should have a security detail, a "Master at Arms" force. 2) Any visiting dignitary or VIP might likely have have their own security detail. 3) Diplomats will have personal body guards, or even Marines. 4) Any criminal element will likely be be armed, as well as any undercover law enforcement agents such elements will attract.Ship owners, light personal weapons / armor.
The adventure I am patching together occurs in part on a gigantic luxury starliner, where display of personal weapons would be intolerably rude.
But from there they will be investigating a murder, a decade-old trade war and ducal coup, Vargr/Zhodani diplomacy, and illicit research Imperial and otherwise, before getting to the nut of the problem, and will need to be doing a certain amount of running around in their own little rock-skipper transport.
So while no one is packing on their hip, unless there are weapons sensors all over the place, concealed carry sounds pretty popular.
