Kappy - First let me say that I am not trying to tell you that you were wrong about the crowding. I just want to tell people that my experience was much different. There were several places on the course where I was literally the only person in a 5 or 6 foot radius. To me, that's not that crowded. I started in Corral B (thanks to a hard-earned 10k proof of time) so perhaps that had something to do with it. There were lots of people passing me too - it's not like I rocketed out of the start and flew by everyone (I run 12:30 pace for a half). And also, in my opinion, I enjoyed running the streets of Anaheim more than I do the highways of WDW. I've only ever done the wine & dine at WDW, so I've not been on the WDW highways during Princess, but as a first time visitor to Anaheim, I found it really cool to see some other parts of the city than just DL. Running through the palm tree-lined retail parts, seeing the high school (or college) bands and cheerleaders, and even the residential areas were interesting to me. I love running at WDW, but I wouldn't hesitate to run in DL again at all. At least not this course. I'm not sure I could go in May, but if they moved it back to January, I'd definitely do it again! Plus I felt like the park parts were better (i.e. longer), than the WDW courses (except the full). AND I have to say I enjoyed not having to be there 3 hours before the start and I thought the finish line was very well organized and found my DH and DS more easily than I thought I would.
I am excited about princess though and experiencing a whole new WDW race weekend! See you there!
