Sympatico,
I read some of that thread too, and several other threads too, that did not shed good light on this management company.
I'm sure they have plenty of rentals without problems, especially in some place as new as WH. If they didn't have a decent number of successful rentals, they'd be out of business, since competition is fierce in Orlando. However, at least on these boards, they don't have a very good reputation for customer service.
I've had no personal experience with them, so your mileage may vary. Go with a positive attitude and just be ready to insist that things are corrected if they aren't just right when you arrive.
