I appreciate the in depth explanations.
So if the Developer Subsidy is approximately $.05 for 2009 then the maintenance fees for future years would still be at an exceptionally low rate of $3.67 + $.05 = $3.72 (not adjusted for future standard rate increases)
That is still $1.32 less than what I am currently paying for BWV.
But remember that each night costs more at BLT than at BWV.
Both resorts have a Standard View category, so that's the best apples-to-apples. Booking 5 nights in a Two Bedroom, Standard View, Adventure season at BLT is 160 points. With dues of $3.67 you will pay $587 out of pocket (dues alone) for that stay.
Booking a 2B, Standard View, 5 nights Adventure at BWV is only 120 points. With dues of $5.04, the cost is $604 per point.
Not much difference.
Now if you hope to stay at BLT, using BLT points for that stay is a lot more economical than points from another resort. Using 160 of your BWV points at $5.04 each is certainly costly. At the same time, using BLT points to stay elsewhere will be very economical. But BWV room categories like Standard View or BoardWalk view will not be consistently available at 7 months.
And that's not even taking into consideration the up-front dollars you will pay by selling BWV points and buying BLT. Assuming you use a broker you'll probably net around $70 per point for BWV (maybe a little more, maybe a little less) and BLT will cost $107 per point.
Financially there are pros and cons to each approach. Selling one and buying the other may be just the right thing to do if it fits your anticipated vacation habits. But don't let the low dues blind you to the other ways you could be impacted.
