So, we are in a similar situation, and I've about had it with unresponsiveness by Disney.
We were originally scheduled for POR, staying Sept. 28 - Oct. 10. Then FD came out, and my wife went to our TA and changed to WL. Then all of the rumors started on the WL thread over here on DIS. Calls to WL and Guest Relations yielded nothing but denials. But that was not the truth. So, as more info starts to be leaked, I e-mailed Guest Relations. That was on 6/14. Never received a response. On 6/25, I e-mailed again. Still no response. Called today. Was basically told that I was out of luck.
If we had a PIN for POR, we would be switching back. Alas, unlike OP, I have never been that fortunate on the PIN front...
I'm not one to complain about customer service. I recognize when I get excellent service (such as with USAA, for example), and I previously had received good customer service from Disney. Not this time. It's been dreadful. I am about ready to take my money elsewhere. Although my youngest son probably needs a couple more years to be really ready, we are about to go spend some time exploring Diagon Alley.
Thanks for allowing me to vent. Just shocked at Disney. Oh, did I mention that this was a celebration of our 12th anniversary? Probably why I am not happy with Disney's efforts, I suppose.
