Best of Oz--enough time for all the optionals or too rushed?

Hey there,

I'm booked for the Best of Oz tour this November and am about to pay out...just had a few concerns that I hope can be addressed by those who have taken this trip (or by Contiki, perhaps):

-Is a couple of nights enough to visit Ayer's rock, to get at least a small taste of the Outback? Is there time to do both the aboriginal walking tours and the scenic flight?

-With only two full days at Cairns (I leave for NZ the 3rd day), is it possible to do a Great Barrier Reef excursion _and_ the Daintree Rainforest? For those who did the intro scuba, was it worth it?

Most people say you can't do Australia in 10 days, but dagnabbit, I think it can be done....especially if you only have 10 days. Right?

Thanks in advance for your response,
:P.
