I renewed Amb today (expiry Sep) using the 200US option with 15000 points and 10% discount on redemptions.
Got a funny confirmation mail from IHG now with title "=?UTF-8?Q??=" and no contents in it.
I am curious when the prolongation appears in my account data and I get the renewal package. Last time it took 4 or 6 months I canīt remember anymore.
