Trying to catch the Celine Dion show sometime after the new year with two of my friends.

Is it just convenient to stay at Caesars? Hotel looks nice enough.
Friends are not 21 yet. One will want to drink and the other one cannot drink. We are not really trying to go to clubs. What are my options?
If schedule permits, is it preferable to come during midweek instead of the weekend?
Any other advice would be appreciated.
thanks
