I put some photos of the surrounding areas of the beach ceremony and the park reception.
The Beach pictures include different cross streets you can park on. A video of the stair to get to the water plus the rocks to climb over. Wear flat shoes or no shoes to get down the rocks. If you can't get down the stairs, there are benches at the top to see the ceremony. You won't be able to hear it but you can see it.
As soon as you drive through the gates of the park you should see the decorations and the "Just Married" Sign.
The parking lot is big and should have plenty of parking. It does have wheelchair accessibility.
