The above post gave you most of the pertinent information. Be aware that getting a 3 bedroom villa is difficult even 11 months out from your dates (the earliest they can be booked), and since we are not less than 7 months out, it will be next to impossible unless you can find someone who has one alreayd booked and can't use it so the intend to rent it out.
You wont really know unless you try though, so call Dave and he can at least check on what's available for your dates. Then if there isn't anything, you'll know up front, and you can start planning for other accommodations.
