disboards.com is an excellent resource I have been to WDW many times, could literally write a book. First, as far as what package to get- that depends on what promotions they have going on at any given time. Depends on how many days you plan to stay, etc. Personally, we always take Parkhopper as part of our "package." Doesn't cost much, and makes it possible to attend two parks the same day. As others said, I could go on forever so I will mention only a few items I think are important to know. 1) Learn about Fast-Pass and take full advantage of it. 2) Key is (especially Magic Kingdom) to be there when the crowds are the lightest. Depends on your family, of course, but if there's any way they can stay up late (even one night for Magic Kingdom) it will be worth it. You can use "Extra Magic Hours" to get in early and stay late. This is the perfect time for kids that age to enjoy all the rides that are age-appropriate for them without waiting forever. AVOID Fantasyland or pretty much Magic Kingdom in general during mid-afternoon. Prime meltdown time. Go back to your hotel and take a nap- yes YOU too. 3) My opinion only, but I would try to steer them away from the character autograph lines. If they get into it, you will find yourself in these autograph lines literally half the day, then they'll be upset if you tell them they have enough. A true lose-lose. You would be better off going to a character breakfast or something. 4) Resign yourself to the fact there's no way you'll see and do everything. I have my own opinions of what your kids would love, but of course every family is different. Depending on when you're going, these four things can turn from important to critical in a hurry.
