There were a few ideas before so I decided to take a swing. I think Disney does the best environment's when it's set in the past, so when you enter DINOland the area will be themed to the "DINO Institutes Open House, 1962." The buildings will take on a older brick style facades and the area music will be a string of 1960's songs with appropriate announcements like the institute had it's own radio. The main building will have been completely redone to reflect the Space Age style architecture, the exhibition space will be updated also but still presented in a period style.
The queue will take you through the class rooms and laboratories of the institute showing the advancement of the "CTX Time Laser." You will be ushered into a meeting room with a old tv monitor with a Walter Cronkite esk host. He will set the scene welcoming you to as "families of the students" and allowing you to be the first to travel back in time through the laser. It will then switch to a young student who similar to the current guy will reset the time circuits. The start will have you be in the center of the huge laser in a huge sterile lab, like Indiana Jones Adventure you will be focused on the laser and you won't see the opening rotate into the following ride path. Story follows you on a mission to rescue a stranded researcher just as the meteor shows strikes. Old effects will be brought back like the physical meteor just before your time runs out and you are teleported back to the lab.
There would also be streetmosphere playing the roles of students and teachers, doing shows that keep up with the latest dinosaur facts and other little skits. For all you know they might pick you to be the visiting relative of them?
See ya walking right down the middle of o'l Main Street USA
