Do we know that reallocating points is officially allowed/standard procedure? I recall a number of discussions in the past where MS refused to reallocate because the nights/reservation in question were fully booked, so cancelling those nights and rebooking using banked wouldn't be possible.
Have they actually made their systems smart enough to reallocate without losing the reservation now?
Also, I forget what happens if you try to reallocate within 30 days of arrival? Do you end up with holding points?
I have an annoying situation where I have banked points which can only be accessed over the phone (sort of like when you try to use transferred points), and I've missed a couple of rooms that have popped up on the website CRA(Page) because I'm navigating MS's phone menu or waiting on hold. The last CM I spoke with told me I should just grab the night online if I see it, and then call in to reallocate, but I'm afraid to do that if reallocation is a depends-on-the-CM-you-get thing. *sigh*
