If your staying offsite I would get there early for the day you want to go to WWOHP since that line gets long very fast. Maybe by the time you go the lines will have slowed down some. Otherwise I would not get there at rope drop since in your other posts you mentioned having purchased the express pass.
The crowds will build the closer you get to the holidays but historically it's not that busy. WWoHP will still be a concern and no one knows what kind of lines to expect then. The rest of the parks should be relatively quiet.
