Not free but included in other costs. Same for BG. Actually now with Bluegreen if you have qualified points you get access to both weeks and points separately which removes the limitation of not being able to trade for points resorts in the weeks side assuming you have the trade power for the resort in question. It also looks like it'll leave the points for deposit in place for the points side using the same membership. One advantage to BG over Wyndham is you can pick the resort and week for deposit where Wyndham exerts more control over the process. Both would be good and cheap vehicles for access and both are good complements to
DVC as are several other options.
