I recently went to the starlight accolades a few times because my supersim needed to win an award to complete the aspiration. The event worked fine for me, no need for a mod to lengthen the time. Only issue is that I have to turn autonomy off. I tried playing with autonomy on and off because I was having problems with aspiration goal where fans have to ask for a selfie. With autonomy on the event was a mess with sims walking everywhere, sitting on the floor and blocking the microphone. With autonomy off every sim sticks to the script. Celebrities take a seat in front of the microphone and the host does his/her job. It works best at speed one, just like restaurants sims seem to need more in game time for an action at speed 2 or 3.
I used the lounge that came with the pack. All I did was add a few decorations.
