Thank you MrsWaldo for relaying your experience, I'm highly interested as we're departing for a similar itinerary (just a couple of different ports I believe) on the 18th of Feb.
I like your idea of dining at the grill while cruising under the Sydney bridge, we might do the same!!
In Isle of Pine we hesitate between Turtle Bay and Moro Island SS tour, so good to know that you enjoyed the latest.
We're still trying to decide what to do in Port-Vila.
I'll be following the rest of your adventures, enjoy your day at sea!
