This was the newest Princess ship we have been on to date. It is also somewhat bigger so there is plenty to do and enough places to go, although the library was like "Old Mother Hubbard's Cupboard", so if you are a reader bring your own reading material.
We had a balcony cabin on the Aloha deck toward the rear of the ship. Comfortable and quiet. Easy access to the rear elevator to access the Allegro Dining hall or go top side for poolside activities and the Horizon.
We ate most of our meals in the Allegro -- breakfast, lunch (when not in port), and dinner basically for portion control. A few mornings we had early shore excursions and had to be in the departure point close to 7 am, which is when the Allegro opens, so we either got something from the International Cafe or in the Horizon Court. On port days, after our shore excursion, we would have lunch in Alfredo's, the grill, or the Horizon Court.. The HC didn't seem to vary their lunch menu much, unlike we had found on previous cruises. Basically same old, same old, so take out of one dish one day, and another the next, and so on. We found the service in the Allegro to be somewhat slow for our tastes as the average time for any meal was 1.5 hours, which made it close to get to a show in the evening. The CD recognized the problem and had 3 shows, one at 4:30, one that was at 7:30, but got moved to 7:15 or even 7:00, so he adjusted the wrong way, and the other one at 8:30, which is close to bed time for some of us (Hey, it's vacation :-))
Room is toward the back of the ship which provides easy access to the back elevator which leads to the Allegro Dining Hall and the Lido and Sun decks. Spacious with a newish flat screen tv. Mattresses hadn't been updated yet -- waiting for the next dry dock, I guess. Balcony was somewhat smallish, deck chairs had to fit sideways, but the deck was great, as usual. Shower has has hand held unit instead of the old wall mounted ones. They switched over to the new electronic door locks on our cruise so we couldn't punch a hole in our cruise card and wear it on a lanyard as we normally do. They are getting ready for the Medallion later this year. Didn't really have any rough seas like we have had previously so I don't know if being that far back and that high would have much motion, or not. It was quiet and peaceful -- good for a restful and relaxing vacation.
