The odd thing is that every night when I get home from work I play a round of Left 4 Dead 2, and one of the modded fan made maps is Pirates of the Caribbean. Come to think of it there's an Indiana Jones ( ride ) and Haunted Mansion ( FL layout ) map too. If you ever want to actually fight zombies in PotC just buy L4D2 and download that level. You can even get off the boats and walk around the walkways used by CM's. The design is so good a CM looked it over and said this is pretty accurate to what the floor layout behind the scenes actually looks like.
