I was just wondering which tour companies any of you would recommend for fully escorted, multi-city trips to Australia? So far I've checked out Australia Pacific Tours, which seem a bit pricey and they appear to leave you on your own for big chunks of time. Qantas Vacations appears decent, although they don't have that big of a selection of tours. There are also a whole bunch I found on vacationstogo.com, although they appear to be a bit interchangeable.
Has anyone traveled with or heard about any other companies that are especially good? I'm interested in tours with nice accommodations, but not necessarily luxury (unless it's at a REALLY good price). I'd also prefer a trip that would last at least approximately three weeks, since traveling from the U.S. to Australia probably isn't something I'd do too often and I would want to see as much in one vacation as possible.
Thanks for any and all suggestions!
