Arghh, she who hesitates is lost - after starting a thread a couple of days ago seeking advice about best ways to maintain Accor ALL status, I went to buy an Accor Signature subscription. There was a 15% sale advertised on the Accor site - fantastic! But then I put in the sale code, and the web site said that the sale code was no longer valid.
Chased through several pages of typical Accor translated from French to Portuguese to English confusing terms and conditions, and seems like the code finished - yesterday.
So I guess the decision is made for me - I will now have wait until Nov/Dec to get the Black Friday deal at the end of the year and thus will have to skip Platinum benefits in Japan in February 2026.
