I don t think they have monthly parking, though I could be wrong.I went to this website and selected monthly and then put in the address of Union Station - 800 N. Alameda - and it showed a map with lot locations and prices. There are a few on Spring St that don t seem too awfully expensive. There is a DASH bus D that goes from Union Station and travels down Spring Street.You might also try calling the people at the MTA building adjacent to the station. We parked there for a few days last year. Maybe someone there can advise you about monthly parking.http://losangeles.bestparking.com/index.��http://www.ladottransit.com/dash/routes/��http://www.westworld.com/~elson/larail/m��
I googled it, thet say long term parking $10/day. I typed in Union Station LA, parking rates .
