I am also interested in hearing everyone's thoughts. I've never been on this trip before, but here are my thoughts:
doing the pre-trip 9-11 OCT over-water. (Seriously. OVER WATER.
What's not to like? It's a once-in-a-lifetime event, just like the
cruise.) I always plan on being at the start point of a cruise two days
in advance in case of baggage or flight mishaps.
post-trip events, I don't know exactly what additional things will be
available at Bora Bora (I suppose simply more water time), so unless
something really big comes up, I'm considering myself priced out of that
one. I'll most likely do an extra day in Papeete because of outbound
flights, though. Need to get cracking on that... And flying through
Auckland is tricky, with that date line messing things up.
