We were at DL and CA Adventure this summer. We kept seeing DVC sales people everywhere. When we asked about a property in CA, they said to let the membership office know. The more people that let them know the better.
We LOVE WDW but we also really liked California! There is so much to do in the Anaheim/San Diego area that we would go at least once a year to CA and once a year to FL if there were properties with reasonable point values available.
This July we ended up staying at an Embassy Suites near DL because it was not wise to use so many points for the DL hotels.
