Our group is still trying to figure out what we want to do. I am guessing we will be going our own way alot, as it would be impossilbe to please all of us at the same time. We are now up to 22 of us ranging in age from 5 to 80.
Not sure about ziplining. I will have to consider whether I am brave enough to try it.
There are currently two different Roll Calls at cruisecritic.com for the 01/31/2010 sailing. You will have to sign up at cruisecritic to see the roll calls, but once you do, they are listed by cruise line and then by ship.
