I saw a post on our sister forum Cruisemates today, that says Carnival is doing away with the normal main dining room breakfast and lunch and instead moving to instituting a brunch that covers the two meals. In other words reducing the dining room options.
I am not sure if this is entirely true, but it seems they are placing emphasis on the "Punchliner Comedy Brunch" and other reports indicate 'this is it' if you want table service for either breakfast or lunch on more than one Carnival ship. A comedian appears for 10 minutes each hour telling stale jokes, and it doesn't start until 9am (or 10am by some reports) so those of us who prefer a sit-down breakfast at 8am may not find this on Carnival in the future.
My point for posting this is that Carnival has been doing things lately that are not popular with their loyal clientele, and it points to their trying to reduce costs (the brunch) while increasing profits (selling VIP perks for $50).
