Well there is only a couple of things that i would reconmend is wait to go to WS for a couple of hours when it opens and then go. The other thing i would reconmend is sence you have two young children is a mid day brake at your resort so you can see the best night show i have ever seen in my life that night. If you want to see more of what ea. park has to offer prepare yourself for long days i reconmend taking long walks in a new pair of shoes before you go to WDW. Don't go to the park that is offering Extra Magical Hour all day long go but only when it first opens for a couple hours and then go to another park that day. Oh yea have your on vacation. last but least plan what you want to do and be flexible.
