Space every place we've stayed has included the local market day/times in their welcome books/material
Hez - I've been to every island.....what do you want to know?
I always book on vbro which I think is now home away - I read tons of reviews and don't read any reviews written by honeymooners, vow renewals or the like - the love everything!
Think about beach access - traffic - the islands all have one major road around them - except Kauai - traffic is an issue
my favs are the north shore of Oahu and Maui - in Maui Keihe (?) is nice and affordable
