That may be, of course. I truly believe that most (but not all) who purchased VGF when BPK became available did so for studios, not the larger units. 150 points will get you a week in a standard view studio for many times of the year and 5 nights for all seasons except Easter and Christmas- New Years.
I wonder if at least a good share of add-on contracts were purchased by those just wanting a few nights to start or end a longer stay elsewhere. That's what we did - I wanted 2 or 3 nights near the MK before our longer stay in a 1 Bedroom at the BWV. It was our first purchase since 1999 and I am now content.

We can walk to the MK from a beautiful resort and then after we move to the BWV, we can walk to EPCOT & DHS and enjoy the amenities of a 1 bedroom. Can't wait to see the refurbished units.
