As one of the few people who have measured in the major theme parks (Walt Disney World) I have found that the need for minor and major changes come at me more frequently than ever before. This is not going to get better, more than likely worse. WDW just removed the "Richard Petty Driving Experience" One Mile Course this fall, due to an unexpected death on the course by a driver. This removed a mile from the WDW Marathon course, tasking me with making last minute changes before the event, because it affected miles 3-4 and 8-9, and construction only completed last week. With Lawyers involved, and Marketing trying to change the park experience, luring repeat attendance, things change in the parks weekly.
It would be a full time job for someone just to keep up with the changes to my courses that go through the 5 parks on Disney Property. And coordinating a measurement through the parks to coincide on the same night is nigh impossible.
I am now proposing that my team goes out and measures sections of the course, instead of the whole course. Like a menu, I would pick and choose elements, and connect them at nailed points. measuring the roads that connect the parks, which requires state police escort via WDW rules, I can forgo that in the future if I have certified those distances separately.
Then, as the parks make changes, I can go out and just measure in a single park, on a night coordinated by the cast members in charge of that park. It may take a number of nights to finalize the measurement, but it should help when making these small changes (or somewhat large ones).
It has been an ongoing struggle with Disney to keep up, and this is the best solution I've come up with. Does anyone else deal with courses that tend to be fluid from year to year, or even month to month? How have you dealth with the challenges of measurements that change more frequently than the wind?
