What's the Effect of Princess Half Marathon?

We are going to be at Disney during the Princess Half Marathon in Feb. I know the crowd calendar takes this into account, but will it affect traffic or anything else? Specifically we’re planning MK that Thurs and HS on Fri.

There will be a letter in your room regarding traffic. No problems that I’ve ever noticed. Lots of medal wearers in the parks…give them a high five!

Thanks for the reply. We’re staying offsite so I guess we won’t get a letter, but I’m glad to hear that you’ve never had problems.
