No set hours, but I would talk it over with an experienced diver, or the captain or DM, and get some advice about what to expect.
IMHO, the specialty classes offered like night diver, boat diver, etc., are a joke.
My pet peeve is the Cecil B. DeJerk who has a movie rig with enough lights to illuminate Yankee Stadium, and ruins the whole experience. It's terrific when everyone douses their lights. That's when the really cool stuff comes out!
