Do you have FSP Points or a fixed week 40 only?
If you have FSP points and you only own Bently Brook than you will NOT have enough points as week 40 is value season and week 52 is prime season. There is substantial difference in points. You could only obtain a partial week stay, but you could do it at the 13 month mark.
If you own a fixed week only, I think it is also a bit dodgy. As you will have to have the following occur: A fixed week owner of week 52 at Bently Brook will have to deposit their week in RCI, and you, a week 40 owner, using some internal trade preference, must have enough trade power to obtain it. There too many dependencies there. Some has to be a fixed week owner, they have to deposit it into RCI, you have to deposit your week with an ongoing search, you have to have enough trade power.
I don't think Bently Brook is in the FAX program, which was the old fixed week internal trade program with Fairfield resorts.
So unless you have different circumstances, I think your chances are slim to nil.
