Luxury cruise ship

I watched the Silver Muse dock in Lyttelton Harbour this morning. I understand that trips on this ship are very expensive, yet there are still 600 people on board. Too many for me, and not my idea of fun, but I guess lots of people sign up for the trip of a lifetime and are enjoying the experience.
Actually I couldn't think of anything nicer to do on this lovely morning than to be sitting atop Mount Pleasant looking down on the harbour and across to Banks Peninsula. Living on the Port Hills and having this view within easy walking distance is my idea of bliss.
