My company is sending me on a "beach vacation" wherever I want to go for 4 nights. I know it's a short trip for Hawaii, but I figured Oahu would work now that they have direct flights from Austin (we were originally thinking St. Martin, but the flight is only 1 hour longer and way cheaper to go to Oahu). The trip cost needs to be under 5k, so that would leave us with a budget of around $700/night for a resort. We would like to be near nice beaches, hiking, bars and restaurants (but I don't really want to stay in the heart of the big city). I was thinking something like turtle bay resort on the north shore, but I'm not familiar with the island at all and would like advice from people familiar with the island.
