From what I noticed the street scenes followed shortly after a show in the Oasis. One on the roof next to the Jungle Cruise, then across the street from there, then in the Tree House. You can usually spot a CM in the Oasis garb in the pathway facing the direction the scene is about to take place.
The scenes randomly placed above the Jungle Cruise was boring and really pointless. Its a great location for a show, but they need to refurbish that entire top floor and really make it accessible for stunts and a zip line that crosses the audience.
