Italy is at the top of my list. I'd like to travel all round Europe & the UK (it's our "long term goal" for when our youngest finishes school).
My husband would like to take me to Tasmania - he lived there for a few years, and we're both keen to do the rail trip up through the middle of Australia (from Adelaide up to Darwin).
We also want to see more of New Zealand and show the kids some more of the country. New Zealanders have a very bad habit of travelling overseas far more than within their own country, and we are both guilty!
