'I need to charge $300000 to earn $3600 toward my maintenance"
Using that ratio would result in
Charging 70,000 would generate $840
which as you pointed out in your post is about a week at a Wyndham points resort.
Your memory and your arithmetic is perfect. My point is thats a lot of money each month ( a whole lot more than I can spend on a card each month) and that there are probably better credit card programs. (I use a PayPal master card debit card that gives me 1% cash back. Not great but I can use the money anyway I want.
My objection to the way the Barclays Card was presented to me is that the salesman coupled it with a sales pitch to make a retail purchase from Wyndham (and thats just not needed)
I wonder...Is there a similar program for Worldmark owners?
