I guess I'm the only one that likes Poseidens Fury.

Granted its not nearly my favorite, but I find it "interesting" If I stay for a week and have a lot of time I will usually do it. It has changed quite a bit to. I thought the first version was the best, not sure why they changed it. I just think its slightly cool. Nothing to write home about. But I like to do most attractions. I would take PF over Sinbad, I did think that was fairly boring, only done it once.
But yes I agree with those that say everything else. Unless you really want to get soaking wet, you could skip Plutos Barges too, but that's about all I would skip.
