No major theming repairs have been planned for Adventure Express this year... However, most of the original theming is still on the ride. The first tunnel (Snake) still has most of the snakes present and the original sound effects, but it is too dark to see while riding. The second tunnel (Spear) still has the spears that come out of the walls, but the train goes through too fast to see them moving and it is also very dark. The first lift (Rickety Bridge) still has the original sound effects, but a few lights out. The third tunnel (Volcano) still has the original sound effects and lighted theming, but most of the lights are in need of replacement. The last tunnel (Finale/Lift #2) has all of the animation and audio effects working, but the train's anti-rollbacks are too loud to hear most of the sound effects. Also, the finale tunnel has plenty of lights that need to be replaced, but they are very difficult to get to as an extension ladder is needed. As for the fog and mist on at the beginning of the ride, it will never return due to rusted pipes and visibility issues on the maintenance roads. Also, the fog in the finale tunnel will not return as it was setting off the ride's fire alarm system. Hopefully this answers any questions about Adventure Express and it's related theming this year!!!
P.S. Typically all of the lighting is replaced once a year on this ride, but it hasn't happened yet this season...
