I just found this thread and find it interesting. I am Accor Plus Silver, and don't book hotels enough to ever likely rise higher in status. Nevertheless, I find the membership excellent value. In March I stayed at the Novotel Darling Harbour for three nights, the first being my "free" night. Yes, only one set of drink vouchers, although the receptionist said we could use them at any time. The best value was 50% off meals! We therefore had 2-for-1 breakfasts each morning, and a wonderful dinner one night that would have been quite expensive. "Happy Hours" was also an good reason to stay there. My previous stay in Sydney was the Sofitel Darling Harbour, again using my "free" night. I am pretty sure I only received a 25% discount on my solo breakfast. Even when I stay at member hotels booked as part of a tour (APT, Trafalgar, etc), I receive my drink vouchers and welcome gift. Just not the points, which I knew would not be applied.
When travelling, I regularly now dine at Accor properties to make use of the member dining discount.
