Mousesavers.com is a good website they do travel arrangements. Kids are free up to age 3 so I agree with the other post about going then. The meal plan is good if you eat all your meals at the park. Although if you are only able to make the trip once, I think ideal age is whenever they break the 50" mark then they can ride every ride at all the parks. There are a ton of more affordable places to stay just off property rather than on site. Although if your kids are still napping when you go any of the hotels on the monorail is invaluable for quick returns for nap time. Also if money isn't an issue there are suites in the animal kingdom lodge where giraffes and elephants will come right up to the window. I am a huge Disney fan and nerd and have been way too many times. If you have any questions feel free to message me or send me an email at Eric.dennis.rush@gmail.com
