I like the old windows and I like the new ones. I don't think they look "cheap" at all. They still allow light to fill the WP and I don't think they detract from the beauty of the place. They're definitely not anything like the gaudy things that I think most people associate stained glass windows to be.The WP is still gorgeous and the most important window, the one behind the altar that showcases Cinderella's castle, will remain untouched.
I'm not happy about the construction either. I have quite a few people coming to my wedding that have never been to Disney and so, of course, I only want their first experiences to be wonderful experiences while they're there; I don't want them to see cranes and dumpsters. But, this is Disney! They're known for the magic they create. I'm going to keep the faith that they'll engineer the additions and renovations to go as smoothly as possible. And, I believe they're trying to do this with as little inconvenience to us brides, as possible.
Chins up, we're getting married at Disney! no matter what, our day is going to be magical!
