I feel your pain
@rottieprincess. Just wanted to say that about a week ago I was able to get a PPO Akershus breakfast for our departure day. So they DO pop up from time to time. My advice (FWIW) would be to make another breakfast ADR and just keep checking. Especially the day before you're hoping to go. Who knows? Maybe it will become available. Then you can just cancel your backup ADR.
I booked all of my other ADRs at 180 days. But I didn't make any plans for our departure day. We have to get on ME at 12 noon to go to the airport so I figured we would just hang out at our resort, pack luggage, and take it easy. I changed my mind recently and just sort of casually looked for a breakfast ADRs when 8:20am Akershus popped up. I wasn't even really looking for that restaurant in particular. So it looks like we'll be going to Epcot on our last day. If nothing else just for breakfast and one last ride on FEA.
I know you mentioned you have Touring Plans searching for this as well. Just make sure you chose the text message option in additional email.
Hang in there! You never know when one might pop up.
