I have an option to book 6-night hotel stay at Westin Lagunamar Ocean resort with Free Night Award OR Cash & Point Award. Below are the 2 options:

Option 1: 6-night stay with 80K SPG points using Free Reward Nights
Option 2: 6-night stay with 36K SPG points + $790 cash

Which of the above 2 options present a better value?
