We did the two night cruise which was fantastic. Two nights gives you a bit of time to explore different parts of the fiord and see more wildlife. The cruise was very well organised by RealNZ. All the staff were excellent and we got very interested commentary from Divesh. He also gave us an interesting evening talk both evenings, with his personal experiences adding interest. My granddaughter said we should only give the cruise 4 stars. Why? Because there was too much food! It was certainly a bit overwhelming to have so many excellent choices in the buffet! I asked about vegetarians for my daughter's family when I booked, but should have asked for vegan. But I didn't need to worry - they had vegan options. Of course you should specify what you need to be sure to get what you want. The scenery is spectacular. Breathtaking. An experience of a lifetime. RealNZ have done a great job of making it possible for us to experience this place.
