Fury of dracula: skipping your turn as the hunters
While passing a Hunter turn has the potential to deny Dracula a card, it will surely make the Hunter turn non-productive. I would consider this to be a wash, generally speaking.

Only one situation forces the player to pass:


  If a hunter is in a sea zone during the night, he must pass.


The benefits/detriments of passing will be situation specific. Perhaps during the late game as the Hunters close in on Dracula it would be beneficial for one Hunter to pass in order to get to the next Hunter. There are many potential scenarios to consider.

That said, passing is generally unlikely. It is in the rules as a realistic option that may occasionally be useful as well as legitimizing the forced pass by making passing an action that can be taken deliberately.
