Crowd level comparison

[alkc71]

i have atrip planned Aug 18-sept1. We are planning arrival day free, sea world, water park and two day on the dark side before focusing on our "lower crowd predicted" days at Disney. We have a daily plan pretty much sorted out. Staying at disney resort entire stay and probably taking taxis outside of the world. I am curious if a crowd level 5/6 at US and IOA compares equally to the way crowds feel at a 5/6 in the magic kingdom. ??
