I am 66 years old but you should not miss Universal Studios. It is my first choice every time I go to Orlando. While some of the rides are for thrill seekers,a lot of them are in simulators that make you feel like you are moving even when you are not.
They have back stage tours of movies they are filming. It is an astounding park. Please google the attractions. Even being an adult, the Harry Potter attraction is fascinating and you can ride a broomstick up into the air.
Also a tip if you are going to Orlando. Take morning tours of the time shares. They usually provide a free breakfast and a free ticket to any of the parks. You will still be at the park by the time the gates open. Just be insistent with the time share people that you are not going to make a purchase after the tour.
I went to Orlando several times with a friend and a relative. We would tour a different time share each morning and get our free tickets to the parks. We went to all of the parks this way. This frees up a lot of money to buy souvenirs and go to restaurants.
Please do not miss Universal Studios.
