Well, orbits are free-fall trajectories: an orbiting body accelerates, but only as directed by gravity, and that accelerates all masses equally. The planet and the things on its surface follow the same trajectory (and a good thing too!), so you'll get small effects similar to tides but no gross 'artificial gravity' effects. Unless you wander inside something's Roche limit.
