I'm really curious about this weekend aswell. I hope to run in Cali in 2018, but so far, the news and rumours since Tinkerbell '17 aren't that great.
If you wander over to the Disneyland Half thread, I've asked several runners to give updates on those issues that arose during this year's Tinkerbell. I'm planning on running the Star Wars Light Side, but not if the problems - especially the security fiasco - haven't been resolved. The pictures posted by runners of the security check spots looked like the Magic Kingdom on New Year's Eve.
