It's never a good idea to rely on any ship for this need. They are far and few between,and can be hihjacked. Renting your own is the best way, and at least if someonee takes it, it would be easier to track it down.
I know someone who left a chair outside of their cabin and poof, so make sure, you keep it in the cabin.
Trip, with her book & tea!
