BIG REPORT!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
I was able to override the no availability problem by following the (crazy!!!) advice of deleting the three of nine I was able to book this AM. I tried to book our of order twice and was stopped. When I booked in order on like the 4th try of booking out of order and cancelling and starting fresh, success with no issues. Used Edge.
Try it folks!!! US site, 9 day park hopper plus, 9 night park stay.
Please report back, and thank you again for the (scary) recommendation.
