In several episodes of TNG, they show them in a big room. (I presume it was a cargo area) Where a stage was built and then taken down. Data performed quartets. There were the theatres that Riker practiced in and then tore down. I would say the same place could easily have been used for the same reason to project a movie onto a wall.
However, when you have a room that can BE a 3D projection of what ever or WHO ever you want, that movie just doesn't cut it. It's like that movie Last Action Hero where the kid got to be IN the movie. It's a lot different than just watching.
