Need to know more since those are rides I have never even thought about in the past
I can tell you about Maelstrom.
Spoilers ahead.............

It is dim when you enter the ride - not real dark, just dim.
You get onto Viking boats and you go up a little hill. There is a deep voice talking to you about going back to the sea if you want to find out about the Spirit of Norway. While the voice is talking a bright light ahead of your boat is pulsating. When your boat gets to the top of the hill, it will float on the water past a number of scenes of Vikings getting ready for trips on the sea.
After your boat passes those scenes, it comes to a forest scene where there is a troll with 3 heads. All the heads are talking and they say that you are entering troll country and they tell you to go away. A creature of some kind is in the water next to them. The trolls tell you to "Be gone" and they say they are going to send you over the falls. Your boat turns a bit and does go backwards past polar bears. The first part is a bit fast, but then it slows down. You go past some nice wooded scenes. Your boat turns around to go frontwards again then. There is a scene of oil mining from the ocean and then you end up in a model of a village by the ocean. Your boat stops there and you get out.
There are some doors to your left after you get out. The doors lead to a theater that shows a movie about Norway. If the doors are open when you come, you can choose to watch the movie or walk right thru (I like the movie). If the doors are shut, you will need to wait a few minute for them to open.
This is a
link to a movie of Maelstrom on youtube if you want to watch. It is not a very good movie, but it is the best one I could find on youtube.
I hope this is helpful. My nephew has Asperger's Syndrome. He likes very precise explanations, so I wrote this the way he would like. I hope you like precise explanations too.
