Is there anyway to find out what room number it refers to?
I just want to know which bathroom/cabinet we own in our resorts...
(Full credit to Micah008, who first outlined the strategy for finding these documents.)
It'll generally be a few rooms. A "Unit" is most commonly 2-4 two-bedroom equivalents. So it could be one Grand Villa, which is equivalent to 2 two-bedrooms. Or it could be a dedicated two-bedroom, a dedicated one-bedroom, a dedicated studio, and a lockoff two-bedroom, which would be the equivalent of 3 two-bedrooms.
You can search the OC Comptroller's web site for the declaration documents that have the drawings and maps of the units. For later resorts, they tend to be listed properly by unit, and they are listed under type "Condo Drawing" and you can search easily. If you have unit 12, for example, you can search on unit 12, or 11, or 10, and eventually find the section that contains your unit.
For earlier stuff like Old Key West and Boardwalk, it's not categorized well, and the documents can be listed different ways, certainly at least "Condo Drawing" and "Condo Related" and the legal description and Unit fields tend to just say some variation on "DISNEYS BOARDWALK". In addition, they rarely have the overall plan map of the resort showing where the specific unit sits relative to the rest of the resort. I'm sure if I could find the main plan drawing of the whole resort I could figure it out. At this point I know that my Unit is two lockoffs somewhere on the fourth floor.
Once you find the drawing and you figure out where it sits on the floor plan and what floor. If you can find a map that shows room numbers you can figure it out from there. Otherwise you'd just have to go the resort, find the right hallway, and count doorways.
