I have been an accor advantage plus member for about three years. I haven't had any problems with Accor Advantage Plus with bookings, including booking free nights. In fact they have rung to remind me that i haven't used my free night and the 12 months is nearly up, admittedly because they also wanted me to renew membership in due course, but this was not due for a few more months. Usually when i want to book free night, i do it by phone directly through accor advantage plus not the hotel, but i have done it either way without any problems. My daughter was recently advised, when she renewed her membership not to waste her free night on a cheaper hotel but to use it on a more expensive one, so will see how she goes! Free nights have usually been at hotels in Australia, not Asia but have stayed in overseas accor hotels also and received reasonable discount.
