We have been on many cruises from Australia, Hong Kong and New Zealand, and this one was by far the best. The ship is beautiful, and the service impeccable -- when I asked at the purser's desk for more recommendation cards, I was told with a rueful grin that so many passengers wanted to commend the staff that they had run out of cards.
The service in the midships bar and the Britannia restaurant were particularly to be recommended. Food in the Britannia was great, if not memorable. The sommelier was very attentive, and soon knew our favorite wine, which was a Cunard blend, so that the bottle was ready and waiting when we arrived.
The alternative dining was not as good -- too much meat and too little garnish, and poorly presented, in both alternative restaurants -- but we were very happy with the main dining venue. And the buffet was wonderful for breakfast and lunch. Plenty of space so the tables were not crammed together.
I hesitated to review this cabin, as everyone will be lining up for it! First of all, deck 4 is a little broader than the decks above, so the balcony is that little bit bigger. Amidships is ideal for stability (always choose a cabin close to, or immediately above, the medical center, as that is the most stable part of the ship). The cabin is approached directly from the top of the stairway, so we expected it might be noisy, but no, it is was very quiet. And only a few steps down to the Britannia restaurant and public areas.
