Curious what others thoughts are for using points towards an air canada vacation rebate. The breakdown is like this:

12,000=100$
29,500=250$
59,000=500$
85,000=720$
170,000=1,440$

I have over 100,000 points and do not have a real need to book a flight anytime in the next two years. Do you think this is essentially "ripping me off" for the value of my points compared to a flight or worth while?
