I will alsocast a vote for the very niceEl Segundo Hilton Garden Inn as I am a light sleeper too. Just be certain to get a room away from the light rail line.
Their shuttle runs every 30 min, takes about 8 min and if you are a HH VIP (isnt everyone at least a HH Gold) you get a FULL breakfast. Also FREE high speed internet in ALL rooms.
