I guarantee the 4 PM will be much cheaper. Day/Night will probably be $120+
But if you're wanting to do everything (Studio Tour, WWOHP, Waterworld etc) it'll be worth it.
But if you're just trying to cram in a few rides (Transformers, Mummy, Simpsons), go with the 4pM for probably half the price. [Although every year of HHN I've crammed in rides, unless you're the type who likes to repeat mazes.]
