Under the Course Designs tab there's courses labelled like 2A and 2B, so it seems that you aren't guaranteed the same route every time. These versions also seem spread onto different planets (2A is on the Moon while 2B is on Venus, for example), so maybe it's the same hole layout but with alternative gravity. Or it's just completely different holes. I have no idea, but I'm hyped now. Thanks for pointing that out!
