if you want to hit all parks do MK and DHS, then for the second day, AK and Epcot.
DHS is basically empty right now. Unless you're willing to skip DHS, spend one full day at MK then the second day at AK and EP.
If you do a full day at MK:
FP Space Mountain, SDMT, and Peter Pan
Go at RD and head to Splash Mountain and BTMR if you are there after the 19th, then to Haunted Mansion, Pirates, then to Fantasyland. After finishing Fantasyland get something to eat and attend your FP for the rest of the day. You should also watch Wishes.
if you decide to go to DHS (schedule your FP for MK for the evening- nighttime (around 2-closing time)), go to DHS at RD and go to RnR, ToT, and TSMM. After TSMM go to Star Tours and head over to MK.
When you get to your first FP do a ride in between and attend your second and so on...
The next day schedule your FP for EP. Schedule your FP for FEA, Mission Space, and The Seas with Nemo & Friends.
Go to AK at RD and hit Kilimanjaro, Everest, and maybe Kali. Try to snag in a Lion King Show before you leave.
When you arrive at EP, go right to Soarin' (it probably will be a decent wait, but it depends when you are going to WDW) after TT, and use your FP for the rest of the night & maybe watch Illuminations.
have fun!
