It still wanted me to sign in through Facebook, so I gave up. But I did read your review on the trip where it appears under "Our Trips." Sounds like you really enjoyed it except for all the flying. That can really get to you.
A friend and I took four trips to Australia and New Zealand independently. Actually, three to Australia and four to New Zealand. We used to go every other year for two months at a time, visiting small townships as well as the big cities and tourist spots. We'd stay over one night in LA both going and coming back, and that may have helped.
I looked at the review listed under yours, which was actually, posed first, and that person found both the Reef and Milford Sound disappointing. It's been more than ten years since I visited the Reef, but I remember it being very exciting even though I don't scuba or even snorkel. We did go down in a semi-submersible to look at the coral. And Milford Sound, we went to twice. Once from Queenstown and once when we were staying in Te Anu. How anyone could find it boring is beyond me!
