Reading the sentiment expressed in this thread makes me understand why Disney largely disregards the desires of fervent fans.
You guys seriously want old, vacant buildings that clearly are remnants of former attractions just sticking around indefinitely? That seems more than a little ridiculous to me. Did you honestly expect the Skyway to come back or something? I know the building is far from the eyesore that River Country is, but people seem to be clamoring for RC's removal because it no longer has a purpose and doesn't fit the area. Likewise, a Skyway building with a large opening in it, while pretty, no doubt, doesn't fit.
There are ways to embrace the past without having relics of it around that obstruct future progress. The Skyway buildings (are and) will be missed, no doubt, but does anyone honestly think that the best use of the limited Fantasyland real estate in this area is for an old attraction building that serves no purpose beyond that of an aesthetic reminder of days past? These changes will open up this area, allow for much needed expansion of the PPF queue, and allow for a better use of the space. Saying that the Skyway is being replaced with a bathroom, and that's disgusting, is reducing this to overly simple and misleading terms. The Skyway is being removed to allow for important infrastructure changes to Fantasyland that will allow for PPF to have a better queue, will facilitate traffic flow in this area, and will also bring newer restrooms to the area.
Plus, who knows, the new building design might actually be quite gorgeous.
