In my case I went to http://www.northshorehostel.com/ and it was great, nice people, quiet, and 10 minutes driving from Kitebeach (I recommend it). I also went camping on the Volcano and Kipahulu.
I got a deal with http://www.hotwire.com/ for getting a car.
It was super windy (7m for 5 days) and the atmosphere was good at Kitebeach.
Overall it was one of my best trip
