Welcome Dan! I love visiting the Big Island volcano national park, Mauna Kea .. my idea of heaven.

There's a thread started for some of the folks who are on this Sydney-Auckland leg of the trip under "Cruise Roll Call and Cruise Acronyms". Click on the link below:

In the "November 2005 who is sailing with me?" thread (same forum), it looks like smilin jack is also joining you and Greg (post is near the bottom of the thread). Link: http://www.luxurycruisetalk.com/ubb/ultimatebb.php?ubb=get_topic;f=2;t=000201

Hope that helps to get you started and that it's a wonderful trip (how could it NOT be??) Need a house-sitter while you are gone? :D

Cheers, Anne
