My vote would need to be, as it was my favorite, is America Sings, with Natures Wonderland second. While we all miss ATIS or PPM, I don't think bringing those back would please anyone but ourselves. Please don't get me wrong! I loved these attractions but just bringing them back wouldn't work today. There would need to be all new technology which could work, but why do something they've done before. Bringing in a new version of the PPM, a mark IV version, would be great and I'm all for it. Just don't bring back something cause we all miss it.
