Do not park in any of the 400 section.
Of course being right next to the beach is amazing. At night you can hear the ocean. If you park in the 400 section the only thing you were here is traffic and it's maddening! The 400 or closest to the main road. It's basically a freeway. You can hear the cars throughout the day and no matter where you park, but they are absolutely terrible if you're in the 4's. Those Spot shouldn't cost more than $20 and I still wouldn't pay $20 to stay there!
