So from what I've gathered, there was some IHG Europe documents that showed that Spire gets "lounge access" as one of the welcome amenity at CP, but I'm not sure if this is rolled out everywhere.

If staying on points and negotiating Lounge Access by paying the fee, that really defeats the purpose because one can do that as a Plat too.

I'm just wondering if there is any incremental benefit going from Plat to Spire and Non-Ambassador to Ambassador, for me they are coupled, when I renew Amb, I get renewed at Spire too.
