If the room service options are too limited, you can always go to the buffet and make a plate to take back to your balcony. In the olden days (when I cruised Princess often) I would fill out the door card to hang out in the evening, but I would write in that I also wanted a hard-boiled egg. I almost always got it. I heard of people doing that for bacon, too, but I just wanted my egg. 🙂
