I couldn't tell you, I've never been. I'm going to look into the total costs. They strongly encourage attendees to stay in the hotel where the conference is taking place, so that you don't miss any of the workshops and are able to really spend time connecting with people. Even with the group discount though its still pretty expensive, I mean its taking place at a Marriot so its to be expected. But if its a life-changing event, which many people attest that it is, well then many would say its well worth the cost. There are some members of this sub who say they've had an amazing time at NSA conferences.
