for the second half of your question:
Poseidon's Fury is a walk-through effects show. The basic storyline has you going into some ancient temple where you're greeted by an overly excited anthropologist (whose name eludes me right now, so I'm just going to call him "BOB" since typing "the anthropologist over and over again is going to get old fast) going on about how the professor has disappeared.
"Bob" finds a few clues into the disappearance, and he leads you deeper and deeper into the temple (basically one show room to the next show room). Some of the effects are quite impressive (the water tunnel (currently seen in the "Terror Mines" haunted house) especially) and then you end up in the final room where a battle between Poseidon and his nemesis (whose name also eludes me right now) occurs utilizing fire effects, water effects, and some sweet projection on water. The best effect in my opinion is the quick dramatic change in the final room.
It's an entertaining show, but certainly not something you should be crying out in agony over missing. It's certainly hokey in parts, and I can't stand the cartoonish appearances of the battling titans in the final room. We skip it 2 out of 3 visits.
