Honestly, it may not be. Before renting a
DVC reservation from a broker or private owner, be sure to do your homework.
There are a lot of differences vs going with a cash room from Disney. Cancellation and refundable options are much more strict.
You have no control over the reservation. You can not adjust it or change names without the owner doing it.
Given some of Disney’s discounts, the savings may not be there to give up the ability to cancel and get your money back.
