You could probably rent the amount of points it would take to stay at CBR, pay for your stay with cash, and have money left over. I guess that would be the way to get the best financial value for your points. Renting points can be a significant amount of work, and only you can say whether it's worth it to you. Money vs. convenience.
I'll tell you how I look at it.....I'm treating my Mom to a GF stay on my points this October. Yeah, it sure does take a lot of points, but my Mom LOVES the GF, and is absolutely thrilled to be going back. I'm thrilled to be able to give her something that makes her so happy. And, I have plenty of points left for the other vacation I want to take this year. So, it's all good, as far as I'm concerned.
Yeah, I guess I could have rented the points, but given current GF prices, I'm not sure I would have gotten enough of a profit to make it worth the trouble.
