I've never been to Disney, and I'm not sure what a crowd 5 means. However, I did go to US/IOA in October 2012. I thought the crows were totally manageable. We did have express passes, however, even on like the Forbidden Journey where the passes couldn't be used, I think we only waited maybe 30 minutes. Rides like superman were approx 15-20 minutes in the regular line. We went to both parks on three separate days. With express passes, we had virtually no wait on most rides.
