Halloween evening starts dark this year. The Moon reaches last quarter on Nov 1 at 20:28 UTC and rises late, so the early evening belongs to the stars.
After sunset the Pleiades climb in the east. Orion follows later, once the trick-or-treat traffic has thinned.
Take a binocular break between visitors. Ten minutes on the Pleiades is a complete observing session if the doorbell allows it.
