Don't have to go all the way to the launch ramp. When you enter the park just go straight to the water. (Not the open ocean launch on your right.) there is a beach right in front of you. It is protected, so there should be no issues with waves. Have good wheels as the haul back up the hill after hooping can be a little annoying with a flat tire.
It is a little bit of a paddle to the middle wall. hooped there once with a couple of friends and we got absolutely 0 shorts and 0 keepers.
If you change your preference you may try the opposite side of the Long Beach breakwall by the 72 street jetty. Easy short paddle, free, close parking and we actually pulled some bugs out of there. Good luck.
