New Starting Line Details:
It does appear after the 5k is over, the buses back to the resorts are over near where we normally get dropped off. Unlike in year's past where the resort bus pickup location was on the east side of the staging area. This new location for bus pickup is the same as it was during MW. This is a good thing for those that finish the 5k before the last starting groups have been released. Historically, you would finish and then wait. Presumably the new location allows you to leave more immediately.
It also appears they are using the security screening area from EPCOT (as I believe they did during MW) instead of the security up near the southwest corner of the starting groups holding area.

Exact match to MW 2022.
10k course map
Exact match to MW 2022, except that the water aid station appears prior to DHS instead of after DHS.
HM Course Map

Starting line is in the EPCOT parking lot instead of on EPCOT Center Drive. I wonder if this is why they originally intended on having designated arrival times. Because I can imagine this getting pretty busy in that area for the HM. Historically, the Princess HM has 20,000 finishers, and the 5k/10k usually have 12,000 or so. So there will be a significant increase in the number of runners pre-race in the area that they normally hold something like 12,000 runners.
The turn off EPCOT Center Drive to World Drive around Mile 1 is new. This is flat (neither uphill or downhill). Whereas the old route was on a ramp and thus had some uphill and downhill components.
We do a jaunt through the MK bus drop off area, which I remember from the 2018 marathon once before.
There's also an extra bumb in Frontier Land in MK heading towards Big Thunder.
The finish from there appears to be roughly the same.
