The ship, the Naia, out of Suva, Fiji, charters over to the Ha'p'ai (sp.?)
group in the Tonga group where there are whale sharks at that month of the
year.  I'm told they also allow their clients do some diving although
limited...I don't believe, from what I've seen of the diving in Va V'au (sp?)
in the Tonga group just north of there -- that the diving is all that
wonderful.  I dived Va V'au and it is very pretty there on land with its
Fijords, channels, etc., and u/w, it does have a few good dive spots.  They've
never been able to sustain local dive operations in Va V'au for any duration.
I guess that says it all.  The weather in July in the Tonga group couldn't be
bettered.  You'll never got hot suiting up.

However, whale sharks in the Hap'ai group in July -- now that's something
else.
