Well, the thing is that we just really don’t know how long it will take to see Star Wars. I would expect it to be very, very busy, but if that is your priority and you have full days at HS dedicated to it, then I can’t imagine it will not be doable. Just realize that you may have to focus a good chunk of your day on Star Wars (and likely still Pandora) and may not get to everything else. FastPasses will help so make sure you snag some, and of course, being there for Rope Drop is a must.
I can’t really give more advice than that until we get a better idea of what we are dealing with, how the traffic flows, ride capacity, etc. Welcome to the Dis, and stick around as I’m sure this will be getting discussed a lot as we get closer to the opening and after. Have fun planning your trip!
