Shuttle vs Driving
Driving can look cheaper until you count parking-lot stress, post-show traffic, and the fact that someone in your group has to handle the whole ride home.
Driving wins if you want total control
If your group insists on its own timing and does not mind parking, stairs, and the exit queue, driving can work.
The shuttle wins if you want the cleaner night
Fixed pricing, no lot strategy, no one stuck driving, and a real ride home after the show.
Best move
If you are comparing because you want less friction, book the shuttle. If you need one vehicle for a full group, book the private ride.
