It's not one of those fancy Caribbean charters where the staff flit around unobtrusively: this is Australia, and the crew mix freely with the guests, and everyone is of course on first-name terms. That makes for a much more interesting experience, as they all have good stories to tell (many involving crocs, naturally.) But the service is excellent and everyone does their job well. Louis will even, when required, do a pre-swim croc-spotting snorkel, which to me seems to be going above and beyond. (I wasn't exaggerating, about the croc stories.)
That is one of the very special things about the Kimberley: as well as being stunningly beautiful, it's an ancient land, and a dangerous one. Calling the Kimberley Quest an expedition vessel rather than just a motor yacht isn't an affectation - that's exactly what it is. All that comfort is just icing on the cake.
