Spain is currently a popular choice for buying to enroll a resale week. If you have a large amount of money to spend the Grand Residence's Fractionals are reported to come out well on MF/CP basis. I've not seen a straight comparison of MF/CP across all resorts/unit type/unit size/seasons.People pay to enroll. I won't do it but out of curiosity, what is considered best value in term of MF per point. I believe DC points are around 0.9 cpp.
It may also be that a Sheraton or Westin purchase to enroll is a good way to go, again, I've not seen the data on MF/CP for all those resorts.
