To put some numbers on this:
In Marriott's pure trust product, '
22 MFs are about 62.8 cents per point. A 2BR oceanfront at Barony Beach Club on Hilton Head in peak summer is 5,400 points. That makes a total fees cost of just about $3,400. A 2BR at
DVC's HHI in peak summer is 337 points. Dues at HHI are $10.07. The total cost? Just about $3,400. (Marriott
point charts are here.)
Buying those Marriott points, on the resale market, would cost you something around $6.50/pt total. (Fidelity is listing Marriott points at about $3.50, plus Marriott's $3 junk fee). So, the 5,400 points cost about $36,000. Buying those DVC points, on the resale market, would cost about $80/pt, or $27,000. That's a real difference, but the HHI points are less versatile.
You can probably get HHI at seven months if you are diligent, which would let you spend a little less using points with cheaper dues. If you used RIV points for it, the dues are $8.38, for a total cost of $2,800. But you'd have to buy RIV points from the developer to use them at HHI--much
much more expensive. Maybe a better choice is SSR. Those points have dues of $7.33, for a total cost of about $2,500 for the week. But you'd have to pay about $120 or so for them, for a bit more than $40K.
But the DVC location is
much less desirable than the Marriott. The Marriott resort is oceanfront. The DVC resort is on the interior of the island. It's on Broad Creek, but it's not the beach. If you wanted one of the "lesser" rooms at Barony (as in: still an easy walk from the beach but a garden view), it would only be 3,725 points, or about $2,400 in dues and a purchase price of just over $24,000--cheaper dues than using SSR points at HHI, and a cheaper buy-in than buying Hilton Head directly. And, it's
still a better location.
If you want a more comparable location, consider Marriott Sunset Pointe. It's just down Broad Creek from Disney's resort. Peak-summer point values for a 2BR there are much lower: 1,400 points. In the pure trust product, that means annual fees are only $900. You can buy those points for less than $10,000.
Edited to add: Looking at these makes me wonder why I haven't bought Marriott.
