Hello US/IOA experts! I've been searching for info on crowd levels at IOA during those 2 days. I know it's going to be busy, but are we talking about not being able to walk without bumping into people busy (like Disney parks during New Year)? We want to see the WWoHP but we probably won't be riding anything since we have 2 little ones. Should we even bother going during those days? Thank you much.
