The beach sequence in Janeway's vision quest used a miniature beach set that was created on Paramount Stage 16.
The holographic environment of the pool hall, Chez Sandrine, was devised as a setting to facilitate some of the character scenes.

We thought pool might be fun, so we created an old Marseilles pool hall, and ended up using it quite a bit."
This episode is the beginning of Janeway's Coffee Odyssey.
