DJ doesn't stay long enough

Hey!

Is there a way or a cheat that I can use, when I'm throwing a party on my home lot, to make the DJ stay for the whole party? They end up leaving like halfway thru, and I go to hire another DJ that, either.. joins the party or never shows up. UGH! LOL...

If there is no work around for this, I hope they make it where we can pay for how long to hire a DJ for... that is all. 😁 TIA
