@margo,
Sometimes it requires a quickie tour to get to see the place to visit later on, but I think I'm going to skip Kangaroo Island. I usually like to stay awhile to walk around to really get the feel for a place, but that's not always possible.
With the options available from Adelaide, I'm planning on doing an all day wine tour - which I'm sure will be enjoyable. I love wine, and go on at least one wine cruise every year. This past January was a wine cruise to the Southern Caribbean, and I already have plans for another wine cruise next January to the Western Caribbean and a Southern France river wine cruise with the same group.
It would be wonderful if we get an opportunity to meet in Sydney; most evenings are free from our tour group, so I'll note it on my itinerary that you might be available on Tuesday evening. Probably some place at the Rocks would be best, heh?
I'm taking my computer tablet with me, so I hope to keep in touch that way.
