I did the 10 day tour with my class from Adelaide to Alice. It was breathtaking. Uluru, King's Canyon, Cata Tjuta, Wilpena Pound, Coward Springs, Palm Valley, Glen Helen Gorge, Lake Eyre... The trip is just made for success, and our guide Benni was just the cherry on top.
Really, I don't think I'll ever experience anything like this ever again.
