Historically Bonnet Creek will get your reservation in their local system around the 2 week mark. Prior to that it would just be in the main Wyndham reservation system. I say historically since I know Wyndham upgraded their systems earlier this year so I don't know if this process changed. It would never hurt to call the resort directly and inquire if they have your reservation in the system.
As Brian mentioned, owners usually get their confirmation of the reservation within 24-48hrs. When you rent, I don't know if there is an extra delay on Wyndham's side when the owner makes a Guest Confirmation request.
Even if there isn't, it really can depend on when the owner makes the Guest request on the reservation. Wyndham charges the owners a fee for putting a guest on the reservation, so different renters will handle things differently. Often they may wait to put the reservation in your name for a variety of reasons such as to protect themselves if you cancel (while they can get a refund of their points up until the last minute, they can't always get a guest fee refund), or to simplify their process of attempting to rebook to take advantage of last minute discounts.
Since Wyndham will send the final guest confirmation to the owner, it would then be up to them to forward it along to you.... which means it could also simply be a case of renter forgetting to pass it along or it's getting snagged for some reason by a spam filter.
Your best bets would be to continue trying to contact the owner directly (Remember, it's a holiday so don't be too surprised if they don't get back to you immediately), and to contact the resort itself to see if they have your name in their system.
