CES - Which Days?

Did everyone get their Preshow Planners yet??? Not much detail on the audio offerings... I'm driving to LV from Flagstaff, and plan to be there for three out of the four days. The question is - which days? I prefer friday through sunday, but the planner makes it seem like there isn't much going on on sunday. Is this true, or is sunday still a happenen' day for high end? Could also be a good day to help people out who'd rather sell demos than take them home. Any thoughts? Is sunday a good day, or should I focus on thursday through saturday. Thanks to the experienced ones!
