As luckyrabbit said Magic Morning is only at
Disneyland. It doesn't happen at DCA. Only guests of one of the three Disney owned hotels get extra hours at DCA, which currently includes hours after closing too for riding Guardians. DCA has extra hours on days that Disneyland does not. Typically SunMWF. Do know that the Extra hours at DCA can impact your visit to DCA. It is a good idea to visit the park that does not have extra hours first thing in the morning.
