I will be getting on at an unmanned station so I know I have to put all my luggage on unchecked, but when I get to San Antonio can I check my bags there all the way to my end stop? That way I won't have to deal with transferring them later. Otherwise when I get to LA I will have to carry suitcases and a carseat to the bus and then have to put them on the SJ all the while helping my two small children.
