We just bought an add on thru The Timeshare Store and the points had to be used before August or we would lose them. Because we had not closed yet and the points were not in the system, MS let me reserve the nights on cash and then let me switch to points when we closed. Question.......can you always do that or is there a catch somewhere? It seems then that you could reserve some nights on cash at a resort that you only had a 7 mo window at and then switch to points when the points become available at 7 mo. Does that make sense?
