For Grand Australia and NZ, I have 2 questions:
1) Day 9 Sydney, the morning activity is a tour of "The Rocks" neighborhood, followed by free time all day. How much would we be missing if we skipped this walking tour? We are considering a day tour of the Blue Mountains instead, and if you have any recommendations for a small group tour please let me know.
2) For Day 15 in Te Anau NZ, was there time to go to the Glow Worm Caves after arriving from the Milford Sound cruise? If so, did you purchase these tickets in advance?
Many thanks.
