Mind you, this is a beautiful spot, and you should go there someday.
For now, simply get up early and motorsail to Marina del Rey. There is a great guest dock at Burton Chase Park. There is also a supermarket and a West Marine close by for things that break on the first day.
On the 2nd day get up early and motorsail to Channel Islands marina.
It would be an easy trip on my Catalina 25 and should be a dream in your 36.
Be aware, it can be foggy, it can be windy (right on the nose). Make sure the GPS works, you have charts, and the VHF works. Join Vessel Assist.
