If I could I would add to your list of bullet points. One being the smoking going on in the aft region of the promenade deck, all so the crew 'has a place to smoke'. Meanwhile that smoke drifts up, up, up and disrupts people's experiences they've been waiting for and are paying (a lot) for on their balcony. Not to mention it makes it impossible for those who would like to walk completely around the promenade deck.
