I have played through the Starlight Accolade Show at least close to forty times. One of the problems I have run into is that if your Sim doesn't move quickly enough, the Host is likely to return to the mic, blocking the Sim from actually receiving the award. Face/palm. But that's also random. I've seen a Host stand back for what feels like ages, as the clock runs out on the ceremony. (Why I use a mod that lengthens the Show.) Suffer me to say, I have experienced both problems.
One cure is to place a second microphone down and allow your Sim to receive it there. I also have a tendency to keep the curser on the microphone so that if my Sim is called, I can click that puppy right away. So long as your Sim accepts the award, they will come home with it in their family inventory. Use the Pause button, if need be. In the lot I use my Sims have to step onto the platform. Sometimes, if he doesn't get up there fast enough, I'll have him stand on the platform to slip in front of the mic at the earliest available moment.
If you are controlling your Sims you can attempt to have them sit in that first row.
Give it a go, you'll quickly learn what you need to do, design-wise.
