First the good: The ship is new and beautiful. The service was good (helped a lot being in the Haven Suites), and the food was really good. Our Butler and Concierge were generally readily available and helped a lot with show reservations and go-kart bookings (extra charge), and dining reservations.
The show Jersey Boys was incredibly good. Several in our group thought it was a better production than they've seen in Chicago and New York.
The BAD: Check the deck plans, and the elevators are WAY spaced out and WAY to busy. Every other cruise ship I've been on has had 3 banks of elevators (forward, mid, and aft). This ship only has 2 banks of elevators which makes for ALOT of walking. I mean ALOT of walking cause its a BIG ship. We were in a forward facing cabin (Haven Suite, but not in the Haven section, more on this later), so to go to the observation lounge/bar we would have to walk about a football field to go to the elevators or stairs to go up a few floors and then walk another football field to get back to the front Observation Lounge/Bar. Whoever designed this should immediately take note. Ridiculous not having enough elevators on this size ship. Even when confronted with the staff about this problem, they all seem to get this from many people.
Tiniest balcony I've ever seen. Barely room for 2 chairs and small table. It's not a wrap around as it appears on the website. Way to much storage space for a week at sea.
