Photo 2 is the west side of Main Street about halfway up. There used to be a short side court there but the Emporium was expanded maybe ten years ago to fill in that spot.
Photo 3 are now-defunct fountains in front of Imagination in EPCOT.
Photo 4 is Tom Sawyer island.
Photo 5 is at the top of the stairs in the entry to what was probably called at the time King Stephan’s Banquet Hall, now Cinderella’s Royal Table.
It looks like first pic was taken over fantasyland while on the skyway. #4 is the bridge on Tom Sawyer’s Island. #5 looks like a chair in Cindy’s castle.
So based on primarily the clothing people are wearing, this could certainly be 1984, though I would say more likely 1985 or 1986 as there are a lot of pastels and brighter colors. That was definitely a “Miami Vice” effect that really hit its stride in those years.
