I attended the 3/1/10 LA event held in the theater area in the back of Cinespace - it's a in a dinner-theater seating style. Local parking in Hollywood is always expensive; I paid $8 - the Cinespace valet is at the west corner of the block on Hollywood. With your printed ticket, security at the entrance would let you past the rope and up the stairs you needed to wind your way back to the theater. Just outside was a small table with name tags but no greeter.
