Just finished a stay at the PH Aviara, and confirmed you can get the 15x points bonus structure as long as you don't charge it to your room folio. Ate at Ember & Rye last night, paid for with my CC -- and the 3x F&B points showed up this morning. Waiting on my room folio points to show up, but don't imagine there should be any issues with that.

Wish I had known all this earlier. Easily had over 1K in meal spend in Maui recently -- that would've netted me an extra 10K points over what I actually received having charged my meals it to the hotel room.
