Honestly, I thought the Harmonious after show was absolutely beautiful- simply music and color and very relaxing. However, the barges were a gross mistake and ruined the view, which is what makes World Showcase what it is.
I've wondered if they could do something like CA does with their show- underwater pipes/features that do not mess up the view, yet would allow good views from all angles. (Water screens aren't my favorites, I must admit.)
I'd hate to see that junk in the AK pond, or anywhere else.
