I posted this earlier this year...
I recommend that you check Ebay. If you don't find the week or price that you want, try to contact some of the reputable sellers on Ebay directly and see if they have the week available. I am going to Bonnet Creek in May for the 2nd time. Last year I purchased a 4 Bedroom Presidential from Farrell's Vacations (8 days 7 nights) for $1295 on Ebay. I purchased it in January for the week of May 9th - May 16th. Ferrell was extremely professional and helpful.
This year I wanted to purchase a week in May again, but I wanted to do it more than 6 months in advance, so that I could make my dining reservations as early as possible. There were no May weeks available on Ebay, so I contacted numerous sellers including most of the sellers that people recommended in this post and other posts on these boards. What I found was reputable sellers that wanted significantly more money than I paid last year - 4 Bedroom Presidential $2300-$2400 and 3 Bedroom Presidential $1900. I finally found an Ebay seller who would reserve a 4 Bedroom Presidential for me in May for $1279. I am sure that the other sellers mentioned frequently on these boards are very professional and helpful, but for me I just cannot justify paying an extra $1000 for the same room.
I purchased my week this year from Adam at Renting-Resorts. I received my Wyndham confirmation documents 8 weeks before my scheduled date.
I hope this helps. I used these boards numerous times last year to help plan my trip and I found the people on here to be the best resources for Bonnet Creek information anywhere on the Web.
