I'm not counting anything on the concierge floor as an upgrade. I get a slight upgrade on almost every stay at both Marriott and SPG properties.

An upgrade for me means something that is obvious ... so, for example, the SLS Beverly Hills often gives me a decent upgrade to a large suite like room but didn't last time because they were sold out. Similarly, the JW Marriott Live sometimes gives me a decent upgrade to a suite but didn't last time because they were sold out.

On the other hand, the W Scottsdale had several upgradeable rooms for sale on the app and insisted they weren't available. The JW Cabo was almost empty and wouldn't give an upgrade.

Still, overall, I'm 30-40 percent on suites at both SPG and Marriott. Places I stay regularly do better.
