What a wonderful thing to do. A few suggestions I have would be: Make up a bag of surprises for him - You can really get some neat "Disney themed" things and give them to him on the trip to Orlando or possibly something each day. Kids love the little things you can find at the dollar stores etc.... and it helps to make the trip time pass by more quickly. If he has a birthday coming up before the trip you could get him some Disney dollars. They can be used at all of the parks just like regular money. You could by him a disposable camera, autograph book, fat pens for characters to sign book with, Guest of Honor badge, or any type of things he will need for the trip so he can build up some anticipation for the trip. Another idea would be to buy him a WDW guide book (such as the WDW for kids by kids). That way he could pick out some of the things he would like to see and do while he is there. Also, you could order the free planning video from Disney so he could watch it and get an idea of what it will be like there. Whatever you do I'm sure he will enjoy since he is obviously loved by you and your husband. Happy planning!
