We do not have a plan for visiting all 4 parks in a single day. That's a fun thing to do, but you'd want to look at park hours and think about what you want to do in each park for your visit to be considered complete. That will vary from day-to-day and person-to-person.
You can set up a separate Personalized Touring Plan for each park, including whatever attractions or experiences you deem appropriate. The plans would have the same date, but you'd configure the plan's hours to represent the time that you plan to spend there.
