It is my understanding that in order to reserve in the 11 month window, ALL of the members points need to be at the home resort. i.e. if the reservation at BLT was going to cost 200 pts and the member had 150 pts at OKW and 50 pts at BLT, then only the BLT points could be used at 11 months and to get the use of all 200 pts the member would have to wait until the 7 month window. If this is true, what is the benefit of buying add-ons at different resorts? I've seen small lots of 50 or 75 points and wondered why one would not just add-on at their home resort.
