Andex, my concern is whether you are considered an "owner" at the other resorts, not just your home resort. Do you get all the same owner benefits, like reduced greens fees. Also, our original West Village deed at OLCC entitles us to day use of the facilities there, outside of our use week. I don't know if being a club member from another resort would still entitle us to that.
I did call, and found out it would be $100 to join, plus the annual $104 membership. Assuming that includes RCI membership fees, that may be an OK additional expense - but will need to find out if that entitles us to keep our original RCI account, or if we would be trading through the club. Many clubs associated with RCI hamstring their owners to some extent, because they don't have direct access to RCI.
We also have to think this through because we now know our TBR weeks would be worth 101,000 club points (half as many RCI points), while our OLCC week is worth 127,000 - the TBR weeks get us equal of more TPU in the weeks system. And obviously, if we join the points program, we lose access to the last minute deals with very low TPU values, unless RCI decides to offere then through points as well (and since so many resorts are now affiliated with points, we know we will have to pay the regular going points rate for those, even at the last minute).
