One other thing is that pricing across all regions is now the same, Milelion has a good article about this.
From October 2025, Stay Plus will require a minimum of one paid night and dining discounts will be capped at 30%, as Accor Plus becomes ALL Accor+ Explorer.

I had mine in Malaysia and paid ~$427 per year with 2x free nights (although these didn't have the limitation). That now drops to ~$345 and also includes 2x free nights (but have to pay for one extra night). Dining was often just me or 3/4 people so not a major loss there and the discounts on drinks and global rates should make up the difference so overall I'm quite pleased.
Now the really interesting thing is unused stay plus certificates multiply on 1 October.
I've got one booking at the Fairmont in Singapore ($415 value as thats the cheapest room rate) and one at the Sofitel Fiji ($370 value) so for my $427 I've got $785 worth of rooms but the gamble is cancelling just prior to 1 October and then rebooking to pick up an extra stay plus. Unless I figure out if you can cancel after 1 October and it still splits into two.
Edit - Found in the help:
So it seems I can sit on my bookings and wait until after 1 October to see if I can extract even more value.
