I believe Accor did pretty poor job by not releasing ALL details by now.
Judging that hotels start releasing their Christmas offers, I would say people are starting to arrange their end of year trips. Accor would miss the opportunity to entice people to reach Diamond.
I also done my planning for the year and if my calculations are correct I should have around 19k status point at the end of the year.
I wont try reach Diamond at this stage as the benefit looks very weak. I better off directing my stays to Marriott hotels to enjoy my elite benefit there.
