As an alternative to bleeding bucketfuls of cash into MVCI, merely titillate them with your interest.
Timeshare tours can be very profitable, points-wise. Inquire of your hotel concierge when staying in areas where MVCI has properties. They'll be very happy to help you out
BTW, we do own developer intervals.....the main caveat with the points exchange program, beyond what has been discussed, is that points obtained thereby cannot be used for stays at MVCI properties, in timeshare units (some MVCI properties have hotel rooms as well, which are a permitted use).
