@franky it’s been open for almost 4 years and you’re right in saying it pretty much hasn’t had a long maintenance period (I think the longest was a month around the time of the Giant Drop refurb). To my understanding the park were able to develop a maintenance plan with Mack Rides that ensure the ride does receive its proper maintenance, without compromising the guest experience. Checks happen out side of park hours, and they ensure they have a sufficient amount of stock for all the parts they may require so it doesn’t delay reopening. The biggest maintenance job is generally on the trains, but they schedule those to have maintenance completed during school terms, so they can continue to operate it with one train. I’ve witnessed first hand how some of these checks occur and it’s certainly an impressive, thorough and effective process.
