|Might I suggest a "Mini Round the World Trip" or a "Round the World Trip".
When you make an international Aeroplan ticket booking, Aeroplan will allow you two stop overs, plus your actual destination. You can also stop at other places for up to 24 hours, if you are there for more than 24 hours it is considered a stop over. Last summer my wife and I flew from Toronto to Jakarta, Indonesia and stayed there for a week visiting Borneo. We then continued on to Shanghai China for a few days, stopping in to Hong Kong for 23 hours on the way. Our last stop was Tokyo, where we spent two weeks criss-crossing Japan. This trip would be considered a "Mini Round the World", and there are distance restrictions on where you can make your stop overs on the way to your destination, but you can actually setup an itinerary where you cross both the Atlantic and Pacific oceans; effectively making it an around the world trip. Our whole trip was booked all in business class for 300K points, 150000 points each.
An actual around the world Aeroplan trip includes five stops I believe, with economy class bookings starting at 200k points per person.
A "Mini Round the World" trip is the best use of points in my opinion, and you can get more information here: http://www.flyertalk.com/forum/air-cana ... i-rtw.html
The Aeroplan reward chart can be found here, and there is information mid-way down the page on around the world bookings:

I know Aeroplan can be a pain to deal with, but there is still some pretty good value in the program if you are prepared to work a little bit to unlock it.
Let me know if you have any questions, or need any help!
