Well... in the MK kids in that range will love Splash mountain, because they see a cartoon right before their eyes and they also get the chance to get wet. What kid woldn't want that. Also in the MK try the Tomorrowland Speedway kids absolutly will love that boy or girl,just make sure they drive, to give them a more fun affect.In epcot deffinatly do saorin, make sure you fastpass that ride or wait in line for 2 1/2 hours. Also, do test track and right before you leave make sure you do Space ship Earth. In HS, I wouldn't highly recommend TOT or Rock and roller coaster, but if they are real thrill seekers ...do it! Just be sure to ask your little ones. Also in HS hit up the toy story ride it is amazing you will thank me later. Lastly, in AK, try going into dinoland they will love everything in there. They can dig up dinosaur bones even. Also in AK try doing Kali river rapids to cool down, and the safari ride the animals rome around freely in your presence. Really Cool!
