Well, it all depends on where you are coming from, what you have already seen, and how much time you will have in each port. You could spend a week in Sydney and not see everything. Please elaborate on the above.
Thank you for your response and I realized I was not as specific as I should have been. We will be arriving in Sydney three days prior to boarding the cruise and staying at the Regent Hotel. We have Opera tickets and plan a visit to the Aquarium. Our first stop will be Melbourne and we have not chosen any tour there and decided to do it own our own. Next, we will be in Hobart where we booked a Port Arthur tour. Dunedin is next and then Christchurch and Wellington. We have pre booked the Taieri Gorge by train and the Tranz Alpine Experience, both almost all day tours, although both giving a lot of exposure to the countryside we hope. We will finish in Auckland where we will have almost all day. Thank you for any comments, suggestions, or further recommendations to our plans.
