Hi. Is it cheaper to self-drive than to take a 3-day tour covering McDonnell, Kings Canyon & Uluru? Saw a tour costing $750 per person by Emurun staying in motels & I find it really expensive. Will it be cheaper by doing it yourself? Am also concern with the safety issues with regards to exploring the terrain with only the 2 of us. Also is the flight out of Ayers Rock that expensive or should we go back to Alice Springs for our flight to Cairns? Thanks.
