I would like to suggest you consider the Concierge level at the Disney Hotel if you can afford it. I have stayed there three times (usually during christmas) and just love it. Whenever I can, we do.
It is great for down time with small kids during the day as well as loading up on snacks for in the park or picking up breakfast to have in bed.
In addition the castmember is very helpful and friendly and will assist you with reservations if you haven't already done so.
Also the view of the fireworks is great and I was surprised that they have the music along too!
The "dedicated" elevator is also another great plus as you can skip the lines of everyone coming back in the afternoon and evenings.
It is also fun to eat and watch the people going to and from downtown disney.
Hope you have fun if you do it too!
