Look over this thread for answers. So far, we've heard from Premier (for the WDW water park part -- and some people did receive the WDW refunds if they requested that -- no DL refunds yet), Signature, Flex, and Deluxe. No reports yet from SoCal or SoCal Select.
For APs who requested the extension, those refunds have not yet been reported. After all, the official announcement only went out last Thursday and today is a holiday. I'd be pleasantly surprised to see Disney moving that fast (and hope that they'd be accurate!).
