Sorry I know this isn't running related but y'all are my friends here... I'm planning a USA holiday late September and we can fly Auckland to Chicago direct, so thinking of starting there for a few days before heading to WDW. How family friendly is Chicago? If we go, how many days? We have visited SF and NYC as a family and though Mrs McN and I enjoyed those cities more than the kids, they were fine with both. And lastly if we go I'll be looking for some running route advice!
