I went to Oahu a couple times for work. I didn't like it. Big cities, bad traffic, everything California expensive. I thought a vacation would be much better spent in Central America or something. But I got invited to see the big Island by some locals I was working with, and man, that place was AWESOME! It was still expensive, but I think it was worth it because it was so beautiful. They had a jungle, a desert, a mountain, a beach. It was just cool. The people were nice and calm too. Not like all the rush and rudeness of Oahu.
