I am thinking of some even smaller things. For instance, in AK, I would love to see some crafts people in the African section, you would be able to watch them work. I would also love to see a smaller show that was more like native dancing and stuff.
I love the que for Kali Rapids - it would neat to do something like that that is really just a walk through attraction. Perhaps you could have some people there to talk to or something.
In Morroco I would love for them to do something with the Fez house - you can walk up stairs and it would be another walk through, this one telling some kind of short story from Arabian Nights or something - there could be little scenes in some of the rooms.
I think the studios needs some kind of quick ride - something that isn't so much of a wait or a time onsuming thing as most of the shows and big rides. But I would do something at the opposite end from RnR and Tower. Perhaps a kind of muppet themed ride like Space Ranger Spin, but instead of lasers it uses water pistols.
As far as little scenes, I would like to see little things in the Animal Kingdom - not just a statue, but something that is a little interactive. I am thinking things such as the rope thing by Indiana Jones or birds outside Tiki Room. Something to give it a little more interest. And for China in World Showcase why not have food stalls and craftsmen. That area seems so devoid of life.
