Overall, the cruise portion of our Aus/NZ trip was good. The itinerary was appealing as it included Hobart, Tasmania, and smaller centers in NZ. We arranged our own flights.
Viking Orion is a classy looking ship with wonderful, friendly fellow passengers. The vast majority were Americans, average age was a good 70. Public areas were well used but comfortable. My partner used the spa and really liked it. We were in a Penthouse Veranda and it has a minimalist decor with lots of storage, small veranda and good bathroom. Kept very clean and stocked with your choices. We did have to deal with the scalding hot/cool oscillations in the shower. This can be mitigated by turning the head on full force and adjusting the temp down until it at least it no longer sears. The bed is a king, good linens but for me way too firm. My sciatica acted up.
I'm aware of the issues around booking shore excursions by suite category but we were able to book exactly what we wanted. Spaces did free up eventually on many showing sold out originally. Unlike some reviewers, I thought the optional excursions were great! Can recommend "Kangaroos and Koalas at Sunset" in Melbourne, "Wildlife Conservation Park and Historic Port Arthur" out of Hobart, "Great Houses of Dunedin", "Sheep Station & Te Mata Peak" out of Napier, and "Geothermal Rotorua" out of Tauranga.
Roomy and quiet. Included pressing service was very good. TV has free movies. WiFi was quite adequate. Ask for exactly what you want in the minibar. Kept clean. All staff friendly.
