I've been on a number of the Grand Class ships before but this one beat them hands down in most areas!
It is so well designed: you never realise that there are so many passengers.
Like other Princess ships, there are main dining rooms, speciality restaurants, bars, a club, theatres, shops and plenty of deckspace around the pools/tubs.
Good points: good size, great balcony, walk-in shower, separate bath, comfortable queen size bed, helpful steward (Antonio) and free laundry for us. Also, not too much noise from other passengers because we were right at the back on caribe deck.Downers: lots of vibration, the toilet sometimes took minutes rather than seconds to flush (keep a log so that you can complain) and a balcony door that kept opening by itself if she ship rolled and one of us was outside---it needs a closing mechanism on the outside!
