It says its at noon, but its actually at dusk instead. So when you get that message just go forward to dusk and you'll find the ? mark. Look at picture from post #501I am also stuck at this point, did everything else available according to the heart guide, tried doing other repetitons of things but still get the stay in room line but no question mark, did you find a way to trigger it?
