Hi Welcome to the boards and congrats on planning your trip
One suggestion is to really research the parks and attractions you want to see. It can be overwhelming your first family Disney trip to see everything. Depending on how old your children are, I would put an afternoon break back at your hotel if you are going to stay on-site.
I know you can add on the park hopper option when your there, I would seriously consider it especially if you are going to be eating in the parks. We did the free dining plan in September. We were not able to always get reservations to a restaurant of the park we were in. It gave us more flexibility for restaurant choices.
I know it is Disney world and there is tons to see. I have been there six times and I never did a water park till this year. I can't believe how much fun it was. We don't have good water parks like that. Blizzard Beach is our favorite.
I don't know what resort you are staying in, if on-site but if money is a factor in your choice and you want amenities that are in a deluxe hotel Coronado Springs is a good choice. We stayed there is September and they have renovated rooms with queen beds. a fitness center and spa and an awesome pool.
I agree with the previous post about the magic express and the internal transportation system. We have had a great experience and wouldn't do it any other way.
We are planning our seventh trip for Sept.2010.
Hope this helps.
