Mary Ilium Shuttle Info

Looking for some info on the shuttle from MEI campground so we can maximize our time listening to the groovy music.
Length of trip: In general, what is the length of the shuttle trip (pick-up2drop-off) relatively early, say around 8am?
Am I correct that the shuttle drops off at the Mountain Village Gondola parking area and we then take the gondola into town? Reverse process at night?
Approximately how long will the trip back to campground, all in, take at the end of the concert?
Thanks!
