I saw Gary Goddard talk about Cirque du Soleil park recently and has said two interesting things:
1. They will have a boat ride which he described as a mix of Jungle Cruise, Navi River Journey and a Cirque show with live performers in the ride space. they will have animal puppets which will allow the "animals" to get very close to the people in the boats and people will be able to "feed" the animals using new technology they are developing for the puppets.
2. Everyone in the parks will be a character including all the bartenders, retail assistants, gate attendants etc. They will all have characters and be a part of the overall universe.
