I can't honestly compare how my 10 yr. old would react since he hasn't been to Universal, but my gut feeling is that Disney would still be his pick. Our kids are 10, 8, and 4, and we feel WDW has so much more to offer our group, that we're waiting until 2004 to take them to Universal. My dh and I have been there. If thrill rides are the 10 yr. old's only love, he would probably enjoy Rock-n-Roller Coaster, TOT, Star Tours, Space Mtn, Splash Mtn, Big Thunder Mtn Railroad, Test Track, Kali River Rapids, and Dinosaur. I suspect there would be more there that he would like and have a hard time imagining any of my son's peers not loving WDW.
