Dwudman,
If you're mainly interested in audio, then book as closely as possible to the Alexis Park hotel, although the San Remo is also a venue for other high-end audio products as well. No matter where you are, there will be shuttles to take you to the different places, especially the LVCC. You may want to consider the AmeriSuites which had a very good rate for CES. I don't know whether they still have availability, but the location is mid-way between LVCC and Alexis Park.
Good luck.
