OK. This we know so far:
The trip will be the last week of March, first week of April, during Spring Break.
It looks like it will be $1100.
It is for ten days.
We will definitely visit: Mauna Kea, Coffee Mill, Volcanoes National Park, A beach on the Kona side, Kona itself, the waterfalls around Hilo
We will probably visit: The Hilo Zoo, the tide pools, the chocolate factory
That’s it, for now. ;)
