I would stay at the Harbor View Inn or one of the many nice Inns on the beach in Santa Barbara (or Hotel Santa Barbara, if you want a little bit nicer place).  Those hotels are about three or four blocks from AmTrak.  The 768 Pacific Surfliner leaves at 6:49 a.m. and gets into the Los Angeles Union Station at 9:35 a.m., if you want to Uber to catch a little bit of the parade, or you can get an early breakfast in Santa Barbara  (Cajun Kitchen is a personal fave, divy kind of breakfast) and take the 9:22 a.m. 774 Pacific Starliner which gets into LA Union Station at 12:10.  2 hour, 45 minutes on the train, half hour to go the 10 miles between the train station and the Rose Bowl.

Good luck.
