Forgot to mention that OKW will not have a pool slide until the end of the year, so if you end up there, and he wants a slide, you might have to pool hop. Closest would be SSR. Be sure to call the resort and make sure it is available for that day. Also, DTD is within walking distance, and kids we have taken have always enjoyed going to DisneyQuest. That is easy too, since it is on the end of DTD nearest to OKW.
