I like the Adam The Woo videos not so much for his repeated acts of rebellion against those who work at Disney, but the fact that he shows you some really interesting places. Who knew I lived about an 1.5 hours northwest of a missile silo located in the middle of the Everlgades?!?!? Obviously Adam The Woo did!
And I like to watch the "Crazy Russian Hacker" (science experiments, life hacks, etc.). Some of his videos are pretty funny.
On the Disney side of the house? ThemeParkReview is good for front seat, Point-Of-View (POV) rides. They do a number of amusement parks pretty much around the world. Check them out! Pretty good stuff!
