Hi Rose! Thanks for visiting the Moms Panel and Welcome to the magic of Disney World! How exciting to be planning your first trip.
The two Parks that I would choose with 2 and 4 year old girls would be Magic Kingdom and Animal Kingdom. Our little girls thoroughly enjoy animals and always have a lot of fun at AK. It is one of our favorite Parks. Epcot does have a few things for little children, like The Seas with Nemo and Friends and the Imagination Pavilion. However, overall, I think you'd find more at the Animal Kingdom for your girls. I recently answered a question about attractions for 2 year olds at AK, you may find that information helpful in your decision making. Click

If you can't get Princess dining for a time that is preferable to you, don't worry. Your girls can still visit with the Princesses and Fairies in Mickey's Toontown Hall of Fame, Ariel's Grotto and Liberty Square. See

Hope this helps and please let me know if I can help you further with your planning.
Have a magical trip to Disney World!
