Hi Charlotte,
This is some information I was given about this pass by an online ticket agent called Paramount International Travel, which is used by quite a few DISers for buying discounted park passes. They sell the pass and sent me this in reply to an Email asking about it.

You won't see the pass listed on the site, but they definitely do sell it. Most people deal with a lady called Rosa, if you want to Email or call.
I hope this helps.
