Hi Joye,
  Thanks for stopping by the Disney Parks Moms Panel with this great question!  
 I would definitely suggest the spectacular Magic Kingdom Park. It is quintessential Disney. There is nothing like walking down Main Street, U.S.A. and seeing Cinderella Castle for the very first time. It's simply MAGICAL! Do take a look at this 
Disney Parks Blog entry for other reasons behind my recommendation. Magic Kingdom Park currently offers 
33 attractions without height requirements. This would maximize the number of rides your children can enjoy together with the entire family. 
 If you could also visit another Disney theme park, I would recommend Disney's Animal Kingdom Theme Park. Right now there are 
34 attractions without height requirements there. Just walking through the INCREDIBLE 
Pandora – The World of Avatar makes this park worth the visit. In addition, it is my belief your children will absolute LOVE seeing all the exotic animals found there too.

 Wishing you an unforgettable visit to the place where 
The Magic is Endless!
