runDisney races are so well organized and managed so well for the large amount of people. The corral system works great, the expo was huge and amazing, and the race shirts are gender specific!
pros:
-mostly flat course
-running through theme parks
-amazing bling
-wonderful plentiful volunteers and aid stations/med tents
-characters on the course
-mild weather

cons:
-race starts at 5:30, must be on a bus no later than 4:00 am
-when not running through theme parks, the highway gets boring
-so many people. VERY crowded
- runs out of merchandise at the expo

I love runDisney races and Princess is such a fun girls weekend. They do need more official merchandise at the expo and maybe a new race course. I love the volunteers and spectators, but am not a fan of the 2:45 wake up call. Overall very well organized, there are just a LOT of runners!
