Definitely do HS for Galaxies Edge! If you’re big Star Wars fans, this is definitely a must do. Aside from Star Wars, there are more thrilling rides in HS than in any of the other parks.
MK is also a must do. Very “magical”, and, in my opinion, really sets the mood for your trip. MK has lots of different types of rides, including many classics. In my opinion, it is the most “Disney” out of the four parks.
The next two are debatable?
Epcot definitely has INCREDIBLE food in World Showcase, never had a bad meal or snack there! I personally also think Epcot has more of a relaxed environment than the other parks. Epcot has always been my favorite of the four, but at the moment, like other people have said, there is just A LOT of construction! Of course Epcot still has some great rides open, like Soarin for example, but others, like Spaceship Earth, are closed. Unless you plan on going solely for the amazing food, I would skip Epcot this trip, especially if you plan on going again one day in the future.
That leaves AK. AK also has some pretty good food, and lots of options. Ride wise, there is some variety. Not a lot of rides in AK. Pandora is gorgeous, and a pretty major reason to go to AK. It really takes you to a whole new world, especially at night! AK also has wonderful shows, I personally love Festival of the Lion King. There’s also a safari ride, and plenty of animal exhibits, and treks you can do as well!
So, I would say do MK, HS, and AK (unless you want to go to Epcot for World Showcase/the food).
Hope this helps! Enjoy your trip!
