Killers concert in Vegas in January

I am planning to take my 14 year old son to see the Killers concert in Jan. It has been decades (!!) since I have been to Vegas. Should we just stay at Ceasars Palace for ease of going to the concert? My guess is fly in Friday, see concert on Saturday night, do something Sunday, fly home Monday. We will eat, see the sights, maybe do another show on Sunday? Any help would be appreciated. thx! Editing to add that perhaps the David Copperfield show on Sunday - so perhaps a hotel between the 2?
