My family went last year during Veteran's Day weekend. We didn't find it to be too crowded. We stayed onsite and had express passes but it still didn't seem to be super crowded.
I think Jersey week is the Thurs/Fri before Veteran's Day this year. That combo will increase the crowds. That doesn't mean the parks will be packed - but that instead of the normally low crowds this time of year, it could be moderate.
