Hi friends, we're planning our honeymoon next March 2011 and were thinking in Hawaii, but don't know anything about it, yet :), which island, where to go, where to stay. We're not looking a 5 stars resort, just something nice and clean. We plan 20 days, but is 20 days too much to stay there? what do you think? Also, where can we go, what to visit (no shopping places at all) just nature, since Hawaii has both things mountains and ocean, excellent combination.
