We did this on my birthday a few years ago too and also managed to throw in 2 resorts besides our own.
We started with CRT breakfast reservations before the MK opened, then rode a few rides right as the park was opening.
Then we took the monorail to Epcot and did the build-your-own-roller-coaster simulator at Innoventions.
From there we took a boat to Beach & Yacht club, where we had ice cream at Beaches & Cream (highly recommended!).
Then we took the boat to Hollywood, road RnRC, and saw a Beauty & the Beast show.
We ended at Animal Kingdom, back when AK used to do EMH at night. I don't think they do that anymore(?), or if they do, it doesn't go very late.
Since we were staying at Wilderness Lodge, we took a bus to Contemporary, ate dinner at their QS place, and then took the boat back to WL.
The next year, we did it again. Again we started at CRT, but this time we went to AK second, then Hollywood, then Epcot for dinner, and then back to HS for Fantasmic. It was fun but exhausting!
If you want to end with MK, I would start at AK, then take their bus to HS, then take the boat to Epcot (maybe stopping along the way for ice cream!), then take the monorail to MK.
Good luck! (Bonus points if you can throw DTD in there as well

)
