Okay, I LITERALLY just asked this similar question 2 weeks ago before my trip! I will tell you what I did on my trip and it TOTALLY worked and was suggested by people on this forum.
With the plan already in place for AK rope drop so we could ride the FoP , I decided to try for the 2 days before the trip to do the "refresh the
MDE" app repeatedly every time I got online. Someone else suggested to take the 1st FP that came up at AK for the other Pandora ride, Navi River, which I did in the days leading up to our trip. Then I would daily go to the MDE app, open that FP for the Navi River and ask to edit it. It would pop up with all of the choices I could alter it to. Well, the day rolls around when I am at AK, standing in the FP line (yes, we stood in the FP line for nearly 45 minutes to ride NRJ!!!) and I used the OTHER suggestion to start looking for FP right as soon as I stepped into the line for Navi and had scanned my bracelet for the FP and began looking for the FoP FP. I did and literally within less than 3 minutes I got one for later that day. I also, during that 45 minute wait in NRJ was able to get 2 FP for the Slinky Dog and the Alien Saucer ride that same day as well. DH and I kind of went on this trip to just do a laid back, not so much rushing and to see the new stuff/rides and restaurants that had popped up in the last 2 years since we had been doing
Disneyland and we literally went to 3 parks in one day and rode all of the newest rides using FP! I was also able to score an ADR at 11 pm at night for the following day to eat at BOG in MK. So, if you are willing to spend a few minutes each day (I think someone suggested trying after 10 pm, EST which is when I tend to get my best ADR's for the following day on my trips!), you can keep hitting refresh and I can almost guarantee you will get one. Especially that far out, you will be able to catch someone who changes their mind and dumps their FoP reservation.
We had booked/planned our vacation only 3 weeks before we left and we were able to eat last minute breakfast at Crystal Palace, dinner at BoG and AK Tiffin's. It really was super easy to pull off, you just have to be patient and diligent! Good luck!
