Ignore the purchase price per point. In the long term, it's immaterial (a few dollars per year per point). What is important is how many points you'll need for your stay and the maintenance fee on those points.
Let me give you an example. Our current maintenance fees are $8.02 at BLT. A week in a 1br is 257 points in early December. Thus, the cost of our room is $2061.
Now, let's move to CCV. Current maintenance fees are $8.49, and a 1br is 237 points. Thus, the cost of the room is $2012.
Now, let's move to VGF. Current maintenance fees are $7.93. A 1br is 340 points. Thus, the cost of the room is $2,696.
Now, let's move to Poly. Current maintenance fees are $7.93. A 1br is 387 points. Thus, the cost of the room is $3,069
Animal Kingdom Villas? Current maintenance fees are $9.64, and a 1br savanna view is 235 points. Thus, the cost of the room is $2,265.
Riviera? Current maintenance fees are $9.06 and a 1br preferred view is 328 points. Thus, the cost of the room is $2,971.
Cabins at Fort Wilderness. Current maintenance fees are $11.88, and a cabin is 132 points. Thus, the cost of the room is $1,568.
But, back to those buy-in prices. I paid $110pp on average for my BLT points. I'm amortizing $2.50 per point per year. That adds $642 to my stay every year until the contract expires. Maintenance fees continue to increase each year, but that $2.50 per point does not. The $642 for the buy-in represents only 23% of the total cost of my vacation this year, and will decrease over time as maintenance fees increase. The number of points and the maintenance fee per point is thus the real cost driver here.
That all being said, buy where you want to stay. My wife and I tried out various
DVC resorts before we bought. Ultimately, we chose BLT for its ability to access the monorail, other monorail resorts, the EPCOT monorail, and the easy walk to the MK. Your decision may be different, based upon what you value the most in a vacation resort.
