I LOVE the spreadsheet!!
Here are some thoughts but obviously take them or leave them
On Friday I see that you have an ADR for Kona cafe. I'd suggest switching your Thursday Boma ADR with the Kona Cafe ADR. That way on Thursday you are at MK so you can hop on the monorail to Poly easy! Or if you could get Ohana for dinner at around 7:15 you could head there from MK and ask for a table to see Wishes. While it's not guaranteed they will try to accomodate. Then you could watch Wishes from Ohana and then walk down to the Beach afterwards and watch the water parade at 9:00.
On Friday you are going from AK to hotel to Poly to Epcot. While you can hop on the monorail to Epcot from Poly you could always move your hotel break up later on this day and do AK then hotel where you eat dinner at Boma and then to Epcot. I think it might make it a smoother day and you'll have had Kona on Monday (unless you switch to Ohana).
On Saturday if you get an earlier CM then you could save some time without having to take the bus from HS and then back. That'll probably be more than an hour. I don't think you'll make it back to HS that morning because the ADR is 10:45. You'll have to leave HS by 10:00ish then with a 10:45 ADR assuming an hour to eat that's 11:45 and then another 30 minutes back to HS. At that point you could probably just walk over to MK from the Contemporary and take the bus back to AKL for the afternoon break.
Have you looked at the menu at Sanaa? If it sounds appealing to you then you might want to switch it out for one of your breakfast Boma ADRs to a lunch or dinner Sanaa. It's supposed to be really good from the reviews and at Sanaa you have a view of the Savannah. While Boma also has great reviews it doesn't have a view of the Savannah and you've got it down 3 times so you might want something new.
Again, just ideas that may or may not fit into your plan!!!
