I enjoy occasionally using my points at HH or Vero. Would love to try HI, not sure when we'll get there, though.
Still, I feel like the best way to maximize value for your points is to use them in WDW DVC. I say that because I know what these units cost to rent them for a night. Even outside the park (which isn't the same thing) I know accommodations similar to DVC units aren't cheap. Similar accommodations in HH or Vero aren't necessarily cheap (especially during peak season) but my sense is that there are more bargains to be found.
Can you rent HH or Vero for cash? I've never even inquired about it. If you can, I'd be curious how those prices compare to WDW DVC resorts on a "per point" basis.
Also, from what I've seen, using your points to stay in a non-DVC WDW resort, on the Disney cruise line, or transferring them into RCI or something is almost always a bad deal for what you get compared to how many points it takes. Part of this is simply that any "non-Disney" resort usually doesn't measure up to the quality of Disney, so you end up feeling cheated.
Again, it's not to say you don't want to do these things - after all, if you have the points and want to take a cruise, why not - but in terms of maximizing the value of your points I don't think it's the best move.
