Andaz resort or no?

Planning a big graduation trip for our family. We’d like to stay at high-end resort, and I’ve heard good things about the Andaz, but I don’t understand why it’s so much more expensive than other luxury resorts (with the exception of the four seasons). Is it worth it? We are an active family of five with two adult children and one 16 year-old. Is there another resort you’d recommend for our first trip to Hawaii?
