Expo:
Great signage at the event and Expo had a ton of booths with volunteers manning stations, etc. Little to no wait (but we dropped by the Expo 2 hours before it was set to close) to collect race kit.

The Event:
Did the 42K, and it was a bit of a blur. Next time, would definitely stay on Disney property as parking and the crowds were a bit of a mess at 2:30AM. A ton of portapotties in the event "village" and everything was very well organized.

Moderate crowding in the first 7k, and in the last 2k, but overall it was a magical experience! There were a ton of Disney characters and more than enough aid stations. Swag was the best I've seen around, but it's Disney, so they *have* to get that right.

I would definitely do this again, if I had the time!
