I ride all of the thrill rides at Universal, Islands of Adventure, and WDW. Coasters are my favorite. For my 53 birthday 2 days ago, I picked Universal and IoA instead of dinner and a movie. Did both parks: rode MIB over 10 times, Hulk twice, Dueling Dragons, Jurrassic Park, Spiderman (twice), and Ripsaw Falls. We ran all over the 2 parks that day. We had so much fun, we went back the next day (Thanksgiving) and did it again. My husband is 53 also and loves them all.
My favorite rides at WDW are RnR, ToT, Splashmountain, MissionSpace, Spacemountain, BTMR, and Dinosaur. At
Disneyland my favorites are Matterhorn, Splash, Space, and Indiana Jones. I seldom ride the tame rides except for Pirates and Haunted Mansion, which I love.
We have two teen sons still at home and love to ride anything they like. The only difference between how I ride now and how I rode when I was a teenagers is now I have to take anti-nausea medication before I hit the parks.
