Celebrity Cruise on the Millenium to Australia/New Zealand

[Fabbenn]

We just booked a cruise on the Millenium to Australia/New Zealand for November, 2008. Has anyone does this particular cruise and can you offer any insight into the excurions that you can take in both places.
How was the ship. I see that it is 8 years old. Any input would be greatly appreiciated.

I have heard that Celebity is a good cruise line. We have only sailed with Holland America.
