Just seconding Diane's advice that Hoop Dee Doo Revue is actually pretty easy to get to, mostly, I guess, due to its proximity to MK. My kids really enjoyed the short boat ride from MK, plus we got to see a little bit of WL on the way, also.
And as Diane said, the boat dock at FW is just down the path from Pioneer Hall, the site of Hoop.
Here's a neat thing about the boat ride. Outside MK, the boat starts in the Seven Seas lagoon. It travels to another body of water, the name of which escapes me right now. Anyway, it gets from one lake to the next via a bridge, and this bridge, which is filled with water, actually goes OVER the road. That's right, you will sail (motor) on the water while going over a bridge that crosses a roadway.
If you've ever taken a Disney Transport bus to MK, at one point the road dips down a little and you go under an overpass. That overpass is a waterway. I'm sorry I'm not describing this very well, but it's really a cool thing, especially for kids.
