That seems to be what i also concludedThe other thing you can do is spend about $1000 give or take for 300K resale points with an annual fee not much larger than that. You have to be patient, but it is doable. It will take you a long time to recoup that $13K in comparison.
Now i am rethinking the Wyndham additional points all together. 486k might be enough in the Wyndham system . Someone suggested Marriot might be a good addition. Maybe RCI points or something else to get different options
