I went on this tour last weekend and for $13.50 (after passholder discount) I thought it was great. I'm the kind of person who always wants to go to the areas of building that they won't allow you in, i.e. what is in that building behind the Royal Palace Theater...what does the backstage at Abbey Stone look like---is it downstairs? Okay, that's a major digression, but this tour satisfied my desire to see forbidden...or should I say 'verboten' areas.
In any case we got to go in the control booth which was really cool to see the ride cameras and see how they operate. And, I asked the ever popular headlight question and the operator said that they only turn them on after dark if they remember to do it and it is dark enough for a sufficient time (in their opinion)to warrant the extra power draw. My tour guide said he'd never heard a headlight question before so a ride operator answered that question. He also said that he *thinks* they are working now. He also said that the old rear-view mirrors were $300 and kept getting knocked off so they sanded the places where they were down and decided to get rid of them. (I think this has already been reported.)
I was very satisfied at our trip within the ride building where we got to view the coaster on a lower level and walked up an adjacent staircase in total darkness to view the ride from a higher level and different perspective. We literally had to hold the stair handrail while putting out a hand to ensure we didn't crash into the person in front of us since they didn't have a flashlight.
Remember to bring a camera since they are happy to photograph you outside in front of the second 'blast' area and are perfectly willing to wait until a coaster is in the frame with you. They are likewise willing to photograph you with the large drop in the background.
I won't reveal any of the 'secrets' or facts about the ride because I'm sure most people interested in the tour want to experience it for themselves. Getting to ride Verbolten without waiting was just icing on the cake.
Currently, tours are held Saturdays at noon. Meet at 11:45 in front of Beste Brezeln und Bier (the pretzel shop in Germany.)
