I'm looking at this from a purely personal viewpoint zap, and things like afternoon tea, lectures, no live music for ballroom dancing etc wouldn't bother us at all. We enjoy lazy days reading or simply watching the ocean, leisurely meals with a bottle of wine, a drink or two in a bar before some evening entertainment and back to the cabin which has clean towels in the bathroom, we're not bothered about the turndown or chocolates on pillow. We don't ask a lot from our cruises, but if the simple things that, in our opinion make it restful and relaxing, are missing then we may as well look elsewhere.
The queues of people booking future cruises will have a different reason for cruising than we do, and are also probably a tad younger too.
