Actually, in a situation like you had at the Radisson, a call to the front desk was in order. Security would have come up and removed the offenders to another room or quieted them down.

The Hilton is a nice hotel; I attend a conference there every year and they are very accomodating; If you came in early, then I would say venture out - but if you've traveled all day, well, you might was to rest up to get in Island Mode for Tahiti.

You could also hop in a cab, go to In-and-Out Burger and bring your dinner back to your room. That's one of the closest ways to eat. Get extra Napkins. Or Hop the Hotel Shuttle and eat at the Encounter Restaurant in the center of LAX. It's quite the happening place these days.
