I hope so too! However after talking with some of the crew that I made friends with, they said that there are no plans to go to the west coast at this time.
I don't know about LA, but here in San Diego, ships have been sailing at or above the capacity for all of this season. My friend does security at the port and is briefed on the numbers two days before sailings.
Virgin's "Vibe" is very SoCal. I think they would do great.
