I agree with pp's that 2 at MK and EP is a good idea. 1 day a tthe other 2 is fine.
And I've been wit a 4 and 5 year old and I would recommend skipping the water parks unless there is a huge interest there. At that age many kids are enthralled by the resort pools - and swimming for an afternoon and a couple of evenings is enough with the 'wet' stuff to keep them satisfied. Besides - the littler kid stuff at the water parks isn't too much different than you can get locally - with wave pools and sprinklers.
So I would skip the water parks and go to the main parks more.

I also have small children, and we are doing the water parks because they are DH's absolute favorite thing. We would love to do Universal and Sea World, but have opted to wait until they are older.
