Own experience
I did it because I m frequent flyer and diamond accor member.
I was considering that it would make sense for the privilege one with the discount from accor and the points.
The discount was counted.
The points NOT COUNTED after over 2 months of sending complaints and writing to Accor and Priority Pass, even that Priority Pass confirmed to them my membership.
Basically, they could counted me my points and kept discussing, but no, better for them to keep me waiting and escalating maybe for another year.
It is more like a scam offer.
Other negatives: If you travel through Germany between EU countries, there is no lounges covered, example : Munich or Frankfurt airports, only lounges useful to travel out of EU
So basically, it was not overall a good deal. I shall cancel it next year, ..
