This was my first time Solo cruising with NCL. It's important to admit that I had a great time on the ship.
Their Studio cabin concept makes a lot of sense, and I hope it's widely adopted by most of the other major cruise lines.
The ship itself is beautifully appointed and is big enough that even loaded with 4000+ passengers it doesn't feel crowded. At the same time, sometimes it felt more like being inside a mall or big hotel resort than being on a ship. There's so many restaurants, lounges and bars inside that I had to push myself to go top-deck and see the ship sail away on a couple of occasions.
Standard studio cabin. It wasn't too close to the studio lounge, so if you plan on spending a lot of time there, be ready to walk. This cabin was on the aft part of the ship, so it had good access to the elevators and stairs that went to the main dining rooms.
