Thank you so much for posting - from what you’ve said, you might of given me some hope. Please could I tell you my situation and you tell me what I can do?
I have a Dec UY, I am wanting a reservation from 26th Dec - 30th Dec 2020. I will have all of my Dec 2019 & Dec 2020 points available, so in my head I originally thought I can start walking from as early as 1st Dec 2019 as soon as I see an opening in these much coveted concierge AKV rooms.
But from what others have said due to needing to change either the status of my points (eg booking with current 2019 points originally and then once we pass over to 1st Dec 2020 they would need to be banked points) or changing the points used (so switching to use my Dec 2020 ones), that I can’t do it - so from what I understand I won’t be able to start my walking journey until 1st Dec 2020, in which case I virtually have zero chance of getting the reservation I want.
I’m finding it very frustrating- as whilst I know not everyone can always get what they want, equally it feels like I’m not even getting the chance to put the effort in to at least try!
