Your offer of an Australian cruise this winter sounds interesting. I am presently booked on a 28 - Amazon cruise with Holland America's Prinsendam. Dates are Nov 20 - Dec 18, 2004. I am booked as a single and am interested in perhaps finding a companion. The cruise has been sold out since last October when it became available. It leaves from Fort Lauderdale and is roundtrip.
I, too, am a 45 year old professional with similar interests and that's what caught my attention about your ad. I did a 10 day Tahitian cruise in June and had a fabulous time. I wouldn't be able to do another (Australian) cruise in January since I'm doing the Amazon this fall.
Let me know if you're interested or would like further info.
