Your best bet to avoid crowds is to get there early. We'll be there at the same time, as we were last year. We had no problems with crowds in the morning, but made an effort to get out of the parks by the afternoon, when they were more crowded, and there seemed to be more people who didn't 'get' the whole Disney thing-- stressing out, exhausted kids, etc. The good news is, going at a busier time of year means that few attractions will be closed. See you at the MK!
