If you go to the RCI online Resort Directory and search for the keyword "Disney", then sort the results by Resort ID and look for the "DVxx" IDs. They include:
The Villas at Disney's Grand Californian Hotel & Spa (#DV10)
Anaheim, CA 92802, USA [map resort]
Aulani, Disney Vacation Club Villas (#DV11)
Kapolei, Oahu, HI 96707, USA [map resort]
Interesting side note: In the rental ID's (RDxx instead of DVxx) for DVC resorts, Aulani weeks are coded for both RD11 (5 night Aulani rental) and RD12 (5 night Ocean View Aulani rental). See:
5 Night, Aulani, Disney Vacation Club Villas (#RD11)
Kapolei, Oahu, HI 96707, USA [map resort]
5 Night Ocean View, Aulani, Disney Vacation Club (#RD12)
Kapolei, Oahu, HI 96707, USA [map resort]
This makes me wonder whether there will eventually be a separate DVC exchange ID (DV12) showing up for exchanging into DVC (Aulani - Ocean View). If so, then DVC Grand Floridian will like eventually be assigned DV13 for its RCI ID#. But if not, then DVC Grand Floridian could eventually be assigned either DV12 or DV13.
