Update:
Las Alcobas is now a Category 8 hotel.... didn't realize that, I checked prior to the Category 8 changes took place earlier this month and didn't see this hotel listed (maybe I missed it), but it's definitely a Category 8 hotel now.
Also, I was told this hotel does not offer the ability to use extra points to book into a vineyard view room. Even prior to the Category 8 change, the Bonvoy rep told me this hotel was not offering the ability to use extra points to book into a vineyard view room.
So it looks like I'll have to rely on the SNAs to get either a junior suite or vineyard view room.
Thanks again to everyone for the suggestions here! I know it's a ways out, but I'll update the thread with the results of the SNA once we're in November.
