Well I'm afirly sure that's the Hosts would want something in extreme proximity to the Convention/Hotels Area..
Lucky Strike Bowling Alley (inside LA Live, next to Nokia Theater)
Hooters (across the street from Convention Center)
Little Tokyo (general area with shops and stuff, be funny for Cheapy to go to Little Tokyo)
Pre or Post E3 PICNIC or BEACHBASH... if this is out of they way for our hosts I will personally drive them to and from at no cost... =D
Any number of Bars... Bring your own Booze Cash....
Renting a Conference Room at the HoTel, and make it a POTLUCK style gettogether... Set up consoles and screens and BAM! Instant CAG party!!
