There are two separate Preferred View booking classifications.
PV - Water & Garden
PV - Boardwalk View
Each of these View Classifications has the same point schedule.
The CM should have told you when you booked which one you were getting. Your confirmation hard copy will tell you which one, as well as the web site if the Vacation Details section is accessible.
Or you can call MS and ask them which one you have.
If you have PV Boardwalk View then you will overlook the Boardwalk & Crescent Lake.
If you have PV Water & Garden you will overlook the pools or canal. You can put in a request for a particular area (ie, overlooking the quiet pool/Community Hall) or "close to elevators" or other such requests.
If you have Water/Garden View you will no overlook the Boardwalk. There are a few of these overlooking the Village Green area.
Hopefully the map below will explain it clearly.
