My wife and I travelled on this cruise as a new year's break; it was out fourth cruise but the first we had done without kids and friends. Being a peak season cruise, the ship was very full with lots of family groups.
Ship
After reading a number of reviews, we were a bit leery about what we could expect but overall the ship handles the numbers onboard pretty well. The Windjammer was a problem during the breakfast peak but otherwise OK. Likewise, the solarium could get a bit crowded on sea days particularly if the temperature on the outside decks was low. Fortunately we had pretty good weather with only 2 coolish seadays out of 4 which is good for NZ.
