Good to hear that you were able to do the rim hike around KC and make it to Alice with time to spare.
Question for all: do you think I can cut my Uluru stay to 1.5 days? - that means arriving AYQ at 09:30 the first day, and then driving to Kings canyon in the afternoon of the 2nd day. In this way, I would arrive KC right before sunfall and get an extra day in Alice.
