Have a look at the modified pics below, it shows the extrance and exits to the station.
Pink = Station Buildings/Maintenance
Yellow = Gif Shop
Blue = Queue Line Building
Red = Track Return Entry (Station/Maintenance )
Green = Track Exit
Purple = Ride Track
Black Circles = Where the ride leaves the station and where it has to join ready for the lift hill. (Guess)
Wouldn't it be great if the track did swoop round inside the gift shop a little at the back, and you could view it through glass on the inside of the shop as it swoops round.
