When I play I have everyone tap the table with one hand during the whole Night period. Everyone's other hand is free to move tokens. Makes noise and movement less obvious.
We play the same way. We have done it that way (we call it "making night noise") since the early days of Are You A Werewolf.
Just remind people to *continue* tapping the table with one hand while they do their nightly duties. I've had players stop tapping to concentrate on being the werewolf/witch, which was a dead giveaway.
