In reply to jamesfrome:
AAC usually gives 50% discount on the accommodation but it does include insurance cover just not the travel element. you will be very lucky to get in. Most people I know who have stayed in it have only managed it because of a cancellation. Not sure if things will be any better with the new hut but there is no way I would have stayed in the old one, it was grim. I bivvied just beyond it.
