I have been to
Disneyland one time, in the 1990s, so take this with a grain of salt. But I would not buy at VDH. The spreadsheets just can't justify it. The dues are high, the
point chart is high, the taxes are high. It just doesn't make sense.
At $10.54, the dues are higher than every WDW resort except Cabins at Fort Wilderness (which no one is buying because of the crazy high dues) and Old Key West. So if you ever use your VDH points to stay at any of those other resorts, you're paying very high dues for those stays. Additionally, this year only 3 WDW resorts had a higher increase than VDH. So it's not like VGF or RIV where dues are not really moving up as fast.
The Transient Occupant Tax at VDH is $2.96 per point. That is bonkers to me. If you own there and use your points there, you're paying $13.50 per point! So even if you got your VDH contract for a steal at say, $150 per point on the resale market, you're paying 150/47 = $3.19, plus the $13.50 = $16.69 per point. On average, that will mean a 2BR at VDH will cost you over $1040 per night. That's more than the average for any of the WDW 2BRs. The VGC dues have the TOT baked in, but they're only $9.52, so for a direct comparison, you'd have to take out the TOT. That makes the comparison dues for VGC $6.56. Remember that the total cost of owning VDH is heavily weighted toward the dues and taxes each year. A 100 point contract might cost $15K up front, but the total dues and taxes will be $78,443. (That's not the actual dollars paid over the contract; that's the total discounted back to the present, assuming a rate of growth equal to the discount rate). This means 84% of the total cost is made up in dues and taxes.
I think VDH could possibly make sense if 1) you REALLY LOVE VDH and value it highly, 2) you buy it resale and are patient for a good deal, and 3) you only visit in the lower cost travel periods on the point chart. And you should only WANT to use those points at VDH because they're really expensive. You can literally rent
DVC points to use at WDW for cheaper per point than buying VDH direct. Even with all of this, I'm not convinced you couldn't do better just booking bounceback offers or the other frequent 25-35% off discounts they offer.
Adding insult to injury on all of this - the onsite benefits at Disneyland keep getting clawed away. No more early entry, no more dedicated park entrance. And unlike WDW, staying offsite at Disneyland can easily still mean walking distance to the parks. I really don't see a reason to pay a premium to stay onsite at Disneyland unless you just really love those resorts and place a crazy high value on them.
Note that none of the above mathematical drawbacks apply to Poly or Copper Creek. Both of those have cheaper
point charts (at Poly you can book connecting studios and it's very close to the point cost of a 2BR at CCV, and it sleeps 10 with 4 showers). Both of those have way lower dues ($8.33 and $9.02 respectively) and $0 TOT taxes. Both have plenty of years to expiration (2066 and 2068, vs VDH in 2074). I would recommend buying Poly direct or CCV resale.
