I am not a DVC owner, but have rented a couple of times. I often side with rentees because I understand their positions, however the above quote says it all. It was a passive-aggressive move to send half payment when full payment was requested and expected, as spelled out in the emailed contract. The OP should have asked if half payment was okay before taking it upon themselves to try and change the terms, instead of "politely" asking after they had stiffed the renter. I agree that the renter was probably scared off by that.
