So it looks pretty good. I do have a few thoughts:
Morning EMH at HS are reportedly pretty phenomenal (I've never done it myself, for a variety of reasons) so I can't imagine using most of that hour as "free time" or "just looking around." If I were going to rally to be out of bed and at the gates for an 0800 opening, I'd be using that time well and having free time and looking around after the EMH was over and the park was getting busier. Otherwise, what's the point of arriving at 0800?
Your group seems maybe interested in Star Wars (I see both Star Tours and the SW night show on your plan). Maybe use some of that "free time" at Launch Bay?
I don't think you'll make it to the 2:00 BATB after Frozen Sing-A-Long. I know what the plan says, but we were late for our 1:05pm reservation at Sci Fi (right behind the sing a long theater) when viewing the 12:30 show. Not sure if it started late or somehow ran long or what, but whatever the case I was sweating hoping we would not be turned away at the podium once we finally reached Sci-Fi at 1:20. BATB theater is a bit of a walk from the theater. I would plan to see the 11:00 show and to TSMM during that a.m. EMH instead.
I also think you're going to have to chose between Fantasmic and SW. It's possible you might catch the end of SW but I think you'll end up enjoying neither show as a result. The Fantasmic Theater is huge and the walk from seating just to Sunset Blvd is long in and of itself. If you sit in the very back and scoot out before the (fantastic) Fantasmic ending, you'll increase your chances. But you'll spend the whole show wondering if it's time to scoot or not. Pick one and enjoy it to its fullest.
