What days to attend CES?

I am planning on attending CES for the first time. I hope to meet people who may be interested in my audio cable products. For a person in my position, which days of the CES would you recommend as important to attend? All 4 days? I am trying to keep the costs minimal, but at the same time I don't want to miss any opportunities. I appreciate any advice you could give. Looking forward to seeing you there.
Thursday and Friday at the least..
Thursday is not the best day to do critical listening, as many systems are not warmed up completely, and in fact some people are still setting up on Thursday morning. Some people come just for the weekend, which tends to be busier. The show ends at 4 pm on Sunday.
