Alright, here goes....
1) Please, please, PLEASE stop construction on Avatarland, your gambling on a movie made in 2009, whose sequels keep getting pushed back farther and farther, if your going to build anything there, if not a true Beastly Kingdom (as previously mentioned), how about Australia, or anything else that doesn't break the overall theme of the park. Yes, I know, Beastly Kingdom breaks the theme of the park, too, but it was originally part of the plans, so it gets a pass.
2) Sharpie me in as another vote to bring back Mr. Toad, the original "Journey Into Your Imagination" ride, (upstairs included!) and the "Wonders of Life" pavilion.
3) Knock off this crap that every ride needs a "plussing" in it's queue/line, most bored people just stare at their phones anyways, so why ruin beloved attractions with interactive stuff nobody really cares about, (Seriously, find me a post anywhere on these boards that starts "Me, the wife, and the kids weren't too sure about **insert name of ride here**, but wow! The things going on in that line make us ALL want to ride again.")
4) Any chance we can go back to the days where buying tickets to holiday parties was worth it??
5) Bring back bus drivers, however packed it was going back to the resort, or however late it was, were ALWAYS fun and entertaining.
