We'll be there around the same time staying on site with FOTL. One crowd calendar (Orlando Insider) just reduced the crowd calendar to moderate instead of busy. While each day might vary I expect with the exception of WWoHP it should be manageable especially with an earlyish start. I also expect that you could still do the Hogwarts express to switch parks and see some of the theming. Reports are that the train sometimes has a very light queue going from Hogwarts to DA.
We will do the HP stuff by trying for early entry and maybe late afternoon.
