You could be right. However, I have my own theory as to the "10 rooms" they plan to reassign:
3rd floor - all rooms reassigned as SV (7316, 7318, 7320, 7326, 7328, 7330)
4th floor - half of the rooms reassigned as SV (7426, 7428, 7430)
5th floor - one room reassigned as SV (7530)
I once had a chance to walk through 7530 (a 2BR dedicated) and the view was awful - with the added "bonus" of direct line of sight from the living room to every person walking across the skybridge from CR to BLT - no privacy at all. I'm convinced they get lots of complaints about 7530....
Based on hints and techniques described by others in this thread, I've attempted to calculate the total points per year for 2011, 2012 and 2013 (based on the above theory for 2013). In my calculation, I assumed for points purposes that BLT contains only 2BR and GV accommodations and used only 2BR DED/LO and GV counts to calculate the total points in the resort per year. In the above 10 rooms I've listed, 7318/7320 comprise a 2BR LO, and 7326/7328 and 7426/7428 also comprise 2BR LO units, so there are a total of 7 2BR units when you count each studio/1BR combination as a single 2BR LO.
2011 - 5,723,488 points
2012 - 5,736,129 points (366 days due to leap year)
For 2013, with the assumption that 10 "rooms" or 7 2BR rooms were reassigned from TP to SV category, the result is:
2013 - 5,717,291 points
If these assumptions and calculations are all correct (a great big IF!!!) there is a 6,197 point difference (or less than 0.11% difference) between 2011 and 2013 which out of a 5.7 million point total, is pretty darn close to "unchanged", the word Disney used to describe the net effect of the change across the total resort.
As another point of interest, if I adjust the 2012 calculation to assume that Feb 2012 has 28 days instead of 29 days, the total would have been 5,719,913 points - leap year added more than 16,000 points to the 2012 calendar. This is even closer to the 2013 calculation - again using the assumptions I've described.
The adjustments to the Bay Lake Tower chart stem from a scheduled reassignment of 10 rooms from Theme Park View to Standard View effective Jan. 1, 2013. This shift is based on Member and Guest feedback, and is designed to better reflect the rooms' views. At Disney's Saratoga Springs Resort & Spa, the Vacation Points required for Treehouse Villas are increasing based on high Member demand.
Increases and decreases within these two Resorts' charts keep the total number of Vacation Points for each Resort unchanged.
I too would like to thank work2play for all the work maintaining this thread. My family has depended on information learned in this thread to make the most of every visit to BLT - a building which we love and which prompted us to join DVC in the first place.
Finally, as to why I've gone to all this effort...... The other theories posted in this thread as to how DVC will reallocate BLT rooms from TP to SV are very credible and are likely to be accurate. I however remain struck by the particular case of room 7530 - this room simply must be reclassified as SV in my opinion. So, my approach to the question was to start with the assumption that 7530 was being reclassified, and then count from there to find the rest of the rooms.
