You are both correct. You CAN NOT cancel a confirmed DVR rental reservation. However the poster must have had a pending request that had not been "matched" or completed so would only lose the $112 initial partial payment or had
very good Travel Insurance. Here is the relevant quote from David's site:
Cancellation Policy
Due to the complexity of the point system and the fact that Owners may have to bank or borrow points in order to secure your reservation, cancellations, upgrades and date modifications are not permitted. The lead guest name must also remain the same due to a rental agreement between the guest and the owner, however, you are permitted to add or delete the additional guests listed in the room with you.
You may want explore the possibilities of adding Travel Insurance to protect yourself against unexpected situations. I do not provide this insurance, but you can obtain a very reasonable quote here:
Travel Insurance Quote
The
$112 part payment is only refunded if we cannot secure your reservation request. This is the only time a refund will be granted.
