I was actually very surprised how reasonable and very similar getting a 2 bedroom MKV was compared to BCV/VWL/BWV when using their own home resort points and looking at cost instead of points.
I wanted to look at the real cost verus the points for a vacation at each resort. I choose to look at 1 week in dream season and the price was similar for a 2 bedroom MK view at BLT and a 2 bedroom at BCV our other home using BLT and BCV points respectively.
BCV 2bdrm 350pts * $4.87 MF/point = $1,704
BLT-MKV 2bdrm 468pts * $3.67 MF/point = $1,717
Not much difference, eh?
Now if you use VB points for a BLT stay, that's a whole 'nother story.
There is the inital investment add into the equation but that would be different for each one of us depending on the buy in price. BLT is selling for higher then the older resorts but there are less years as well. Recently we were looking at VWL resales (which has the same point structure as BCV) deciding if we wanted to add-on there or BLT. If I add in the inital investment, spread evenly over the remaining years (I know it's not really that simple, but humor me)...
VWL ($80pp + ~2.5 pp (closing cost))/ 33years = $2.5 pp/yr * 350 pts = $875
BLT $107pp/50years = $2.14 pp/yr * 468 pts = $1,001
Total Cost VWL 2bdrm $1,704 + $875 = $2,579
Total Cost BLT-MKV 2bdrm $1,717 + $1,001 = $2719
Not a huge difference ~$140 especially since threre are lots of variables that can change. Like the BLT's MF could go up after the resort is sold out.
I think the moral of the story is to factor in your MF for the points you are using to really know the cost.
