What I liked most was the beautiful view from the upper decks, the relaxing feeling …
That was the best part: The outdoor whirlpools were excellent, but there were too few of them for a ship of this size and number of guests. I would recommend adding more whirlpools or providing a larger swimming pool. The existing pools are quite small and seem more suitable for children than for adults.
