You might ask the mod to change the date in the thread title, as Dec is a pretty long time & it's not 'til toward the end of your OP that one even finds 12/30.

Also, I would hazard a guess that most are out of town on the 30th for the holidays or just zooming around doing holiday things since it's a Sunday.

If by chance you don't find someone to do the I-n-O thing, what I'd recommend given the timeframe of your layover is to catch one of the hotel shuttles (Marriott, Hilton, etc) to the hotel, and then catch the free "Ocean Express" shuttle from the hotel to downtown Manhattan Beach. MB is a fun seaside town about 10-15 minutes away from LAX - has a pier, shops, restaurants, bars, galleries. The Ocean Express runs on a regular basis, and the hotel bellman have the schedule, so then you'd catch the OE back to the hotel & then catch the hotel shuttle back to LAX. Just a thought...

Cheers.
