We always use EE mornings and generally stay in that park all day. I have read suggestions about using EE, then around lunch time going to another park. We have never done that becuase to me it seemed that by the time you exit one park, wait for a bus or monorail, get in the other park, you have used a lot of time that you could have used seeing attractions in the EE park. What are some ideas from those who have swapped parks?
