On the other hand....
You have paid for your DVC points. Figuring $5 per point dues for the year (I know that's too high, but I don't want to mess with the math, so I'm rounding) the 29 points would be $145 at most and no tax. Even the weekend night would be $260 (again no tax so you are still better off than rack rate). IF you aren't going to use the points for something else before they expire AND you don't want to mess with renters, using the points really isn't that bad an idea. Granted I am not figuring in the buy in cost of the points, but as DH the economist says, that is a sunk cost at this point.
Renting your points has it's own cost - depends on how much you value your time and how much aggravation you are willing to put up with.
