What I don't understand is why you didn't just post your vacation on the disboards for someone to take over?
I have found that when you get reasonably close to the actual vacation, someone is usually out there looking for the same dates.
Recently, because of some peculiar circumstance, I found that I had to cancel one reservation less than 30 days out. I had no trouble finding someone to take the reservation over, and for more than I had originally rented it out for!!
The time period that you had was long enough so that there shouldn't have been any problem in finding someone.
I have a policy with my renters that as soon as someone wants to cancel, I work with them to immediately post the reservation to see if someone wants to take it over. The few times it has happened, I either got the full amount, or more!!
In looking at your post and the various other things you have said, I think that you might have rented from someone without much experience renting out their points.
Also, I don't see that the renter did anything that was not in the contract. However, he should have responded to your emails.
Try calling him. That usually works best.
Good luck on your trivals and I hope you get to Disney soon.
