I started out with 170 points in VWL. Added on 130 points at BCV because we love the proximity to EPCOT and October was impossible to get in BW or BCV for 9-10 days. My kids were in college and high school and it was just my DH and myself so a studio was perfect for us. Added on 30 more at both resorts a few years later - the ones who thought I was crazy (my children) for buying a time share in Disney now are 25, 27 and 29 and want to go. So we have enough points to give them a vacation if they want. We also booked for them for college graduation and honeymoon and still have for us and friends if we want to "treat" them. The disadvantage of adding on is that the price per point always was higher than when you first bought. Depends on how many times a year you want to go, the studio vs the 1 BR and looking down the road at your wants and needs.. It's nice to know that when the winters get to us with snow, ice and cold weather there is an escape with our points.
