I would recommend contacting dreams unlimited travel agent. I had my boss use them to stay at a non Disney hotel but under the preferred Disney list so they could book the FP at the same time and they saved her money by going through them.
You do NOT need to book these hotels through Disney to get the 60 day fastpass and EMH, and you can OFTEN get better hotel rates by going through the hotel directly or using a 3rd party like Priceline or Hotwire. The privileges are through the hotel, and are not influenced by how you book. Use hotel points, book through a discount website, or book direct...it;s all the same.
