Originally, my idea on how to "fix" this attraction was to retheme it to Ms. Frizzle's Magic School Bus. The ride system works as it's a bus and in the 360 room they could do stuff like fly up someone's nose or fly off into space. I still think it would work and the kiddies would love it. But I think I have a better idea.
Summer of Love featuring The Grateful Dead.
Ok, The Grateful Dead is from the Haight/Ashbury area of San Francisco. They were basically the house band for The Summer of Love (1967) in Golden Gate Park. They also used to travel around on Ken Kessy's bus named Further which is actually at The Smithsonian now.
So repaint the busses to look like ^^^. Retheme the alley to the Haight and Ashbury district.
Have the "party scene" be a Grateful Dead Concert with hippies dancing to the song Truckin'. Which is the encore. Then have the bus pull into the 360 scene playing animation that looks like the video below (start at 2:40) playing a compilation mix of dead tunes.
The exit shop could be filled with Grateful Dead and other Woodstock alum merch.
Done. Thank you, where do I pick up my check?
