The 2013 prices are here:

I have not seen the 2014 rates as yet.
As you may know, if you stay at a local hotel they may provide you with a free lift pass for the duration of your stay. 'Duration' is often defined as 24 hours, so you can check out from the hotel and then get a lift up to your hut for free.
The Saas Fee website will have the details when they are available.
