Since you asked. . .
The information is available from records filed by Disney Vacation Development with the Orange County Comptroller. Since they are public records, they can be viewed and downloaded free of charge from the OCC website. Each time DVD declares more Units for a
DVC resort, it files a Condo Related document that contains floor plans of the phases being declared. Once you find the right Condo Related for the resort that you want, then you match up the floor plans with a good map of the resort.
There are multiple Condo Related documents for each resort. The first AKV declaration was in January 2007 and there have been 32 declarations since then. The 32nd Declaration was recorded on May 17, 2013. Usually, but not always, the last declaration contains a list showing the dates of the previous declarations and the Phases/Units that were declared in each. If I'm looking for Unit 106A, I check for the Declaration that contains Phase 106. I then search the OCC database for a Condo Related about the time that that Declaration was filed.
OKW is easy to identify the Unit because each Unit number corresponds to an OKW Building Number. AKV, BLT, and VGF and pretty easy for me to find the Units because the Condo Recordings are easy to read. Aulani is extremely easy because the Aulani Master Declaration has a complete listing of each Unit showing Villa numbers, floors, view category, and even Building (wing). I wish DVD would do that for every DVC resort!
BWV is one of the toughest resorts for me to deal with because I'm not familiar with the layout of the resort. There are so many twists and turns in BWV's layout that I'm never sure if I'm in the right hallway.
If you really want to play around with these condo related documents, I can give you some more detailed information about working with the databases. But for most people watching paint dry can be a lot more entertaining.
