I believe the MVC Collette tour is for 2 persons. Still, it is a huge gap: $9,180 vs. $13,464. My points cost me roughly $0.60 per point so for me it will come out to $11,880.
What the points "cost you" (presumably in MFs) is often how salespeople pitch it, especially if you have a low MF week, but it really is not the best metric to use in my view. The MFs are a "sunk cost" which you pay either way. Now the question is how you use that week, so things rental income become a much better metric to use when comparing alternate uses.
For example - in my case NCV Platinum converts to 3475 DPs and has MFs (including county taxes) of $1550.
The "cost per point" is about $0.45 (MF/DPs), but if I am not using the week in a given use year and am considering a Collette Tour among other uses, then I can do one of the following mutually exclusive options:
1) Rent out a peak summer week for $3500 (value of about $1/point).
2) Rent out a non-summer week for $2800 (value of about $0.80 per point)
3) Elect for 3475 points and rent those points for $2400 (about $0.69/point).
4) Use of Collette tour where they price a $9180 trip ($4590 mentioned above x 2 people) for 19,800 points ($0.46 per point)
The "value" of the Collette tour is about the cost of my MFs and people averse to using the rental market may take them up on it. But it's a terrible value compared to some other alternate uses where you end up with cash in your pocket and can then book the trip with cash. It's those alternate uses that will ultimately impact my decision.
Based on the above, even converting to DP is a lousy use of a NCV Platinum week which is why, when I don't use it, I prefer to rent it out and then rent points from others. Even if some of those get lost due to non-transferability, I still come out way ahead.
