Every theme park has special things for that age group, but a lot of it depends on their personalities, and willingness to try new things. At MK just about everything was a hit, can't think of anything my girls didn't enjoy. A few things can be very dark, my girls had "magic wands" that they were given as gifts and they light up, it was a good way to ward off the scary darkness without disturbing others. EPCOT was another hit, Living Seas and The Land were the biggest hits, Honey I Shrunk the Audience is a great show but not for all kids. The line was too long for Test Track or DD4 would have loved to ride it. MGM had the highest and lowest points - the Playhouse Disney show, Beauty and the Beast show, Muppets and Star Tours were great. They were terrified by the noise at the Indiana Jones show and we weren't even in the theater, just near the area. We knew this, but Great Movie ride can be really tough for kids - very intense in a couple areas. At AK many families find Its Tough to be a Bug sends their kids into fits, it sure did for us. And they begged to see it, but we left about 2 minutes into the show. Pool time was huge, and the character meals (especially Garden Grill in EPCOT) were big hits. We had a great time, so much so that we will be back in March!
