The quickest way is via the East Coast of Oz. Qantas fly from Sydney to LA, then you need to connect to United and change once on the way down to Orlando. Alternatively Air NZ fly out there, but its always via Auckland. Much nicer aircraft/staff than United, but the additional hour or so in NZ is an extra bit, on top of an already incredibly LONG journey!

Or you can get a round the world ticket for a little bit more, and throw a trip into England on the way around, stopping in Asia as well, so lots of nice breaks! Singapore Airlines usually have a great stop over deal,(Singapore Splendour) A$1 for the first night, and around $45 a double after that (40p and 18 pounds) and throw in free transfers, half price meals,free trip to the Zoo, free nighttime Safari, free travel around Singapore, and a free trip to Sentosa Island. Its a sensational deal, and we do it every time. Can't be beaten for value!
