Hey! I did run this one, and it was fun!

Off the top of my head--

Positives:
Running through the castle!
Energy of lots of people!
Great costumes!
You get into the park on monday.

Negatives:
You have to be there really really early. And I am used to early.
Once you are on the property, prices are high, so you need to plan ahead.
It isn't the most exciting outside of the parks, but on the other hand, there are very few marathons that are exciting for 26.2 miles and that's ok.


All in all, I think it is a fantastic first marathon. It is even more fun if you can convince family and/or friends to join you!
