You can buy a metro day pass, go down the escalator and buy at the kiosk in the underground rail station which is located across the street from the metro parking lot and in front of the Universal Studios entrance. Just enter in your license plate & you're good to go. Make sure you go before 8PM otherwise you'd end up walking downhill to get back. This is $3.50.

You can do the above for any metro parking lots. You don't have to use the metro, they don't check if you actually used the metro as long as you bought a day pass ticket. Yeah so what?

You can park INSIDE universal studio lots, such as ET or Jurassic park for free AFTER you buy any AMC movie for $5.00. Then just go online and ask for a refund BEFORE the movie starts. This is free parking.

You can park in the residential areas around Universal City but it's a 15 minute walk to the free shuttle.

It's also free to street park at Griffith Park, near the observatory (not the entrance) as their kiosk system have stopped working for quite a time now as of this date.

Thank me later.

Is there any cheap or free parking or public transportation where I can park nearby and it takes me to Universal Studios? I'm going to visit 4 times. I don't want to pay $35 each time for parking.
