LAN LANPASS - 21,000 km expiring -- Where should I go?

I am based in SFO. I have 21K km expiring in a month; these are leftover from a SPG transfer that allowed us to fly to Cabo back in the day.

What might be a reasonable use of these km for a short weekend trip somewhere? I would be willing to add a few more SPG if I needed to.

Any ideas?? Thanks!
