Parts of the new course I liked, and parts I hated. I loved running a fairly quick quarter on the track at WWOS - it felt nicely spongy after all the concrete. The multiple tight turns, and narrow width made bottlenecking pretty much inevitable, however.
It was nicer to get to AK earlier, and onto Oceloa earlier, since basically there is no shade from AK until you get to DHS, but the sidewalk coming out of AK to the parking lot was reduced to walking, because it was so narrow. All it took was a few people in front to walk abreast there, and suddenly everyone was walking.
Likewise, the steep ramp for the speedway - it bottlenecks, and I would have been much more comfortable taking that at something a little faster than a stumbling shuffle, both up and down. YMMV, but it is narrow enough that, again, a couple of people walking abreast can ensure that everyone walks, like it or not.
If the course is going to get to the Contemporary so earlier, I think Disney really needs to look at lighting that area under the water bridge. It's dark, especially early in the race, and very easy for people to fall and get hurt.
I liked the course in general, but it felt really, really crowded this year. Granted, I was running at a very slow pace (took my camera and planned on a lot of pics, which I got), so maybe it is always like that, but I think that Disney either needs to lower the cap, or move the start earlier and put a little more time between the waves.
