Hi M., my family and I have gone to Disney every year for the past 30 years. My biggest tip to you is don't try to do everything. We have two usual day plans; the first we go to a park or water park in the morning and then come back for a siesta or just to relax and the hit another park at night. The second is where we eat breakfast and swim at the hotel and then hit the parks around 1:00pm. I could go on and on about tips we have for each park! Also a great website is www.allearsnet.com. They have info about everything, times, parades, menus, character dining, you name it, they got it. Try to figure out where you want to eat (especially if you want to to do the character breakfast in the castle) and then book early. Also I suggest staying on property, they have hotels for every budget, and now offer a free shuttle to/from the airport. You also can enjoy early morning or extra magic hours at night. And if you can definately take a stroller for your young one or two. We dont rent a car as we are disney nuts and don't go off property. If you want to ask any specific questions once you start planning, feel free to email me at ____@____.com don't miss the nightly entertainment; at the Magic Kingdom, if there are two parades, opt for the second, not so crowded, that way during the first you can hit some rides. And at Epcot, you must see Illuminations at least once and then stroll slowly to the exit, you miss some of the rush!
Have fun planning!
