Make a timeline of events that occur whether the PCs intercede/interfere with or not. This way, the PCs can see events happening around them and can make decisions based on their observations. The masquerade ball in Whispers of the Vampire's Blade has a short timeline like this.
Example: 15 minutes-Lucan locates Neya. He greets her and leads her to the dance floor.
Obviously, the more detailed the timeline, the more it will seem to come alive.
