Even though my DD loves MK the very, very best, she still likes Epcot much better than I do!!! The rides there, except Body Wars and Fast Track, are all tame, and the kids are fascinated with the fountains. The countries in World Showcase have kids activities also. You might want to skip some of the exhibits, though---they can get boring to a kid---even a 30 something kid

I think the 5 yo will like Illuminations too. You might just want to go even if for only 1/2 day--maybe split the day with AK or something

But, if I were choosing between them---I'd say MAGIC KINGDOM above and beyond ANY of the other parks!!!!!! It is the epitome of Disney Magic, and nothing else at Disney World could ever match up!!!! Probably the 5 year old will be more interested in the other rides like Peter Pan, Haunted Mansion, Buzz Lightyear, Goofy's Barnstormer, Pirates of the Caribbean, and much, much more this year. Your family might have to split up on some rides to keep both kids happy. They are not going to like the same rides at this point in their lives, and really there is nothing there, short of Alien Encounter, Space Mountain, and perhaps Splash and Big Thunder Mountains that should be too much for your 5 year old. Your DS will love it, although her taste may run to Winnie the Pooh, Small World, the Carousel, Dumbo, and Peter Pan! They would probably both love to explore Tom Sawyer's Island also! And don't forget to take them to see Country Bear Jamboree

My suggestion would be 1 day MK, 1 day AK, 1/2 day Epcot, and 1/2 day to full day at MGM--there really is less at MGM and Epcot for that age group than the other 2 parks.
Have a Wonderful day, Eeyore
