Its too bad you can't put the rest day in the middle, but I understand the Thursday is your DD's actual birthday and you want to be in MK for that. Overall, your plans sound good with plenty of time to fit in extra rides while you are there. I like that you didn't succumb to the temptation to squeeze too much in. That said, there are ways to easily fit a few more things in.
For your MK day, if the park opens at 9am, you can enter Main street at 8am. The Welcome show starts at 8:55am. If you want to watch this, you won't be able to take the jitney up Main Street after the park opens. I'd plan it a little later to maybe take it DOWN Main Street? That said, with only one park day - I'd think adding a "real" ride or two would be a bit more magical (although the jitneys are definitely fun).
Anyway - I would suggest:
7:45 - wait for MK bus at POR
8:15 - 8:45am - arrive in MK, check out Main St, have breakfast, and absorb the atmosphere, and take some time to take multiple photos with the Castle - I always NEED at least one awesome shot with the Castle
8:55 - Welcome Show
9am - Peter Pan (go through the Castle
immediately after the Welcome Show is over)
9:10 - Winnie the Pooh (both Peter and Pooh are walkons at this time and are very short rides)
9:20 - Enchanted Tales with Belle (usually a walk on this early - so you can use your FP+ for something else)
9:45 - 7DMT with FP+
I'd also consider adding in a meet with talking Mickey on Main Street. There really is something magical about a photo with Mickey when visiting WDW.
For your AK day, since Affection Station won't open until 10am, I would consider flipping your Pandora explorations to the morning (when it may not be as busy to wander since everyone will be rushing to the rides) OR doing your character meets first (note - this week, Baloo & King Louie's schedule is from 10:30am-1:30pm & 2:40pm-6:00pm). I like to check
wdwent.com for this type of info as he publishes the new schedules every week. Times do change as the times guide is published weekly so make sure you double check.
OR what would likely be better - move your Safari to 9am at opening. The animals are really active in the morning, its a nice way to kick off an AK day and you save your FP+ which can be used for: Nemo (a Broadway quality show), Flights of Wonder (very engaging bird show), Kali River Rapids (you do get wet on this one though!), or a Mickey and Minnie meet.
