The linked webpage says to "Call Member Services to check availability." So this is apparently just a limited listing of potential destinations, using RCI's web interface to search/look at options.
I don't see anything remotely near Anaheim, as an alternative for a Disneyland vacation, rather than the higher points cost of nightly stays at Disneyland Hotel or the new, small DVC there.
Don't see Wyndham Alexandria for Washington DC visitors - it's a great urban location that I'd think would interest some DVCers.
Don't see WorldMark San Francisco - excellent urban location and resort.
The Hilton and Wyndham locations in Las Vegas and Hawaii are included. So I'd think that someone who wants to use HGVC points or Wyndham points to trade into DVC ought to have no problem. Though, apparently, some have been unable to snag a DVC match by using Wyndham points in RCI Weeks so far, even though there have been sightings. It remains to be seen whether this is a temporary issue or not... maybe larger points amounts are needed?
There are no Orlando area listings at all, just as they did with II. This eliminates the option of trading out and staying offsite when DVC is booked solid during prime holidays, high DVC points. It remains to be seen whether DVC's decision to limit their Members' access to area resorts will somehow translate into a new policy for RCI, of restricting RCI members from trading their Orlando weeks into DVC or not. If this shows up online in black and white, it'd be more convincing (and concerning) than the comments of one RCI VC. It'd indicate a change in RCI policy.
As a past HHI Marriott owner, I was restricted from trading that week through II into DVC's HHI resort. But RCI's HHI owners may do so now, if they want to try the themed resort, since there are so few RCI HHI resorts on the beach. At least the DVC there has a beach house with a shuttle over there during the daytime. Staying off-beach is fine for us when it's too cool for beach swimming anyway and the beach is rather windy.
Very interesting linked page, Alwysonvac. Will be curious to see if or how it changes over time, as DVC Members request additions to the resort list or comment on their exchange experiences.
