Hey Pug!
The Sahara is not bad and you could get a $25/night room usually from Monday to Thurs. Just remember it's on the other end of the strip (North)! If your exhibit is at the South End (The Venetian and such), it's gonna be tough, although there's a monorail that you might be able to use... check this!
and this! and this!....hope this would help you out!
Most of the hotels in the south end and in-between of the strip are in the $80??? and above range~, and unlucky for you, your schedule falls on the expensive part of the week!
Check this for some good hotel deals:

If you plan to indulge, don't forget to pada your pockets.....LOL! Bring a good pair of walking shoes......most places are within walking distance and January is nice walking month in Vegas! Let me know if you need to know some other stuff and I'll try to guide you to the right places.......if nothing else, don't miss the
Tourneau Time Dome located in the Forum Shoppes in the Caesar's Palace Hotel and Casino.
Enjoy and have fun!
