I am planning a trip to hawaii.
heard maui (hookipa) should be great for windsurfing.
does anyone knows about the cheapest accomodation, car rental, dayly costs (food&fun), flight from australia (brisbane)...
Is it accepted to sleep in a van, can i buy a van as a tourist, camping?
Is july/august the right time to go there?
Do you know any place (private) to stay in exchange for some work (electrician)
All helpful information much appreciated
