I agree with above. Figure out which three things in each park are most important for you to do, and accept that anything else is gravy. Plan to start early and stay late. I might consider visiting MK and AK one day and Epcot and DHS the other. If you’ll have a car, use it; if not, provide more details i.e. are you starting from a Disney resort or from offsite, and folks here will try to help.
