OK after all the advice i've been given (thankyou!!) i've decided we will be taking the train to Universal and also into Hollywood. Now i've been researching wether to take the Amtrak train or Metrolink, both seem ok.
I can take the Amtrak on a weekday for $30 return (for two) but it doesn't leave until 8am getting us to Union Station at around 9am then we have to get to Universal which will make it around 10am when we arrive, we can get there on the tour bus at the same time for less money, but we have to leave at 5pm with the tour bus.
If I take the metrolink to Union Station it costs $38 return (for two) but we can leave much earlier.
Both options also mean we have to pay again for a metro day pass once we get to Union Station which costs more money again.
We could go via metrolink much cheaper on a weekend but they only have a train that leaves well after 9am so that rules that out.
We will be taking the train to Hollywood no matter what but i'm now wondering if we should take it to Universal as it just seems like a lot of hassle and extra money for a few extra hours in the evening.
Am I reading these schedules/fares correctly? If someone can let me know a better way that would be great. We would prefer to go on a weekday into Universal, Anyday for Hollywood would be OK.
