1. a much better IASW that's longer with better puppets, a better ceiling, better effects
2. updating IASW to be more culturally sensitive and diverse can most easily be done with a whole re-do, especially with plans to add IP dolls
3. updating the song to highlight the various languages of the world better and to re-orchestrate it to be less cloying and repetitive
4. moving IASW from Fantasyland opens up access to all the land behind HM and RoA better than the current plan to go thru Frontierland's train station (in that area).
5. IASW in Epcot is the perfect all-ages ride to introduce the concept of World Showcase... which is thematically better than being in Fantasyland. Is world peace a fantasy?
