Okay, I have one cruise on Armonia, so here is my take. She is a lot smaller. Not a problem for me. She does not have the bells & whistles. There are lots of lounges for sitting, relaxing, conversing. That is intentional. All of this class were lengthened. The only cabins that originally had balconies are the suites. All of the other balconies were tacked onto the outside of OV cabins, just like Carnival did to the Fantasy class. All of the inside, OV, and balcony cabins (other than suites) are the same size. I can’t pinpoint exactly where the joinings are for the section inserted, but I think the connections to the vent system were not perfect. We had the first cabin after the balconies, 9225, and it was excessively humid. Such that any papers left in the cabin became limp. Pick it up and it drapes over your hand. It was also chilly, but when the temp was raised, it became even more humid. When we left the cabin and walked forward, it was like moving from one climatic zone to another.
The MDR was weird. There was a forward and an aft portion, with elevator coming down in the middle. And another elevator to the aft, so there was a constant stream of people through during dinner.
We did enjoy our cruise, which was lengthened from 7 - 9 days by a hurricane.
