I just got off the phone with MS, and she was able to reallocate my points for my existing reservation at BLT and use up all my banked points! I actually called and initially asked for a new reservation, with the plan to cancel my existing one afterwards. However, she says one of the days (12/19) had no availability for a 1 BR Bay Lake View. So, I figured it wouldn't hurt to ask to reallocate the points. To my surprise, she is it was ok, now that I am at the 7 months mark.
There is method to my madness. Now that I have freed up my 200 BLT points, I was able to modify my April 2011 trip to BLT from a 1 BR to a 2 BR Bay Lake View, using my home resort advantage. I love the flexibility of
DVC system!
