First, there is a great set of video interviews done by the folks at Get Her Onboard with 4 couples including Pat & Ali of Bumfuzzle who were interviewed on this site. I had an excellent time watching and highly recommend you take a peek.
Second, the women over at Women and Cruising have asked 15 women what they like most about cruising -- a very diverse set of cruisers and consequently responses to the question that I found fascinating.
